Just back today from a split stay which included five nights at BWI club level. I wanted to take a few minutes to write up our thoughts of the resort for anyone who might be interested. I'm going to be doing a full trip report, but it's going to take a bit to get all that together (pics and all) so I thought I'd do this first.
We were in room 4252, with a garden view and view of the Eiffel tower in Epcot off to the left. It's just what I requested. Very quiet and peaceful. It was a few rooms in from the CL card access door and down the hall a bit from the lounge. The room was very clean, and mousekeeping did a wonderful job daily. No towel animals (except for check in day) but everything was truly impeccable. I ate most of the chocolates left on our check in day by myself.

Turn down service was lovely. The saltwater taffy was tasty and several times we received these adorable cards with nostalgic pictures and quotes on them. Sweet.
The actual resort is AWESOME. I absolutely loved it. My husband thought the decor was a bit frilly for him, but I thought the theme was fantastic and so well done. It wasn't too confusing to get around in or anything. We both loved how throughout the resort there were cozy little sitting rooms--lots of places to relax. We really enjoyed being on the boardwalk and several times we ate at the BW pizza window and at BW bakery. Both were great. DH had a chicken salad at BW bakery that was really good, I had a tomato/mozz sandwich that was delicious, and a tiramisu that was divine.
We spent one morning at the pool and it was awesome. The kids loved it. My older son went down the waterslide several times and I joined him a lot. It was a blast! I'm really glad we were able to fit some pool time in this trip. A word of note--if you want life jackets, they are over in Community Hall by one of the quiet pools and you need to check them out. They're not just out by the pool like the are in other resorts.
Of course, you seriously, seriously cannot beat the location. It is perfect. I think the walk to Epcot was ten minutes, if that. DHS maybe 15. Watching Illuminations and then just walking back, not having to deal with the crowds--just priceless. I loved the feel of the boardwalk--so fun and festive. And the view across the lake of BC and YC was beautiful.
As for the club level experience--I honestly don't have any complaints. I think by now we've all heard the accolades sung about the BWI Innkeepers Club CMs and all I can say it--the praise is true. They are amazing people. So kind, friendly, genuine. Joe and Anita conversed with my younger son (who would talk for hours to a tree) and didn't mind at all--they seemed to be enjoying themselves. Pete, who checked us in, was so kind. Anita was a COMPLETE blast and so much fun to chat with. Lorenzo sang made up songs about my DS2's name that had me chuckling. Also, one morning my DH wanted to make egg salad with the hard boiled eggs they have, and he asked if they had any mayo. They didn't, but Lorenzo went all the way down to the first floor to get him some. Totally and completely over the top kind. Cecelia was so wonderful to me--one morning when I was taking breakfast back to the room for my family, they were out of trays and she gladly helped me carry everything down the hall. It really is true that these people are one of a kind.
The lounge is pretty big. We never had a problem finding somewhere to sit, no matter when we visited. They always had the tv on, usually to Disney XD or something that made my boys happy.

The food was always replenished when it started to run low--they never ran out of anything. The schedule is:
6:30 - 7 am: coffee
7 - 10:30am: breakfast
11am - 4pm(I think): snacks
5 - 7pm: evening appetizers
8 - 10pm: dessert/cordials
Breakfast was oatmeal with brown sugar, raisins, cranberries, and slivered almonds, hard boiled eggs, mini muffins (blueberry, choc chip, or lemon poppy seed), breads (banana, apple, cinnamon), grapes, strawberries, cantaloupe, bagels, croissants, yogurt. In addition to coffee there was tea, OJ, whole milk and skim milk, and chocolate milk.
Snacks were goldfish, trail mix, choc covered almonds and raisins, the house made chips, swedish fish, cookies.
Evening appetizers--they always did a selection of cheeses and crackers, and rotated things like tabouleh and pita, vegetables and dip, lamb or pork skewers (I can't remember which meat), samosas, rice pilafs. All very good. They also put beer and wine out.
Desserts were things like little cannoli, baklava, small choc cakes. They had several cordials to accompany them.
All that said, we almost definitely won't stay CL again. While the convenience is great, for our family it doesn't justify the cost, as we still spend a ton of time in the parks. But I am so happy and grateful we were able to try it!!
Now, the downsides. Honestly, there aren't many. The lack of onsite counter service is kind of a bummer, but not too big of a deal. Heading out to the BW really doesn't take long at all.
We had one experience that was bizarre. We had a package shipped to the resort and I realized one morning that we hadn't heard if it had been delivered. I checked online and it had been, two days prior (it wasn't crucial that we had it immediately so neither DH nor I was thinking about it). I learned it was in the Business Center. They never called me or anything. Odd. I went down to pick it up and I had to pay a processing fee. That was annoying, but mostly i don't understand why they didn't at least call to let us know it had arrived. At CBR, where we had just been, we actually had two packages delivered and each time they just brought them up to the room. So I am not sure what happened over at the Boardwalk. Hardly the end of the world, but sort of odd.
But truly, the biggest downside was the buses. The BWI appears to be picked up first and dropped off last virtually everywhere, and while it generally guarantees you get a seat when going to a park, getting there takes a really long time. The buses stop at BWI, then Swan, Dolphin, and if there's still room, the BC and YC. And on the way back from a park, the BWI is usually the last stop, so we were on there a long time.
It felt to us like the buses were more crowded this year as opposed to last year, but that could just be our perception. Nevertheless, the bus situation kind of sucked. I realize you are sort of taking public transit

but travel time was more than I'd expected.
All that said, the BWI is a beautiful resort and I really loved it. Truly a gorgeous hotel. If you are considering staying there, I would absolutely recommend it (as long as you are okay with buses to MK and AK taking a while).
