I am finally getting caught up on life after returning from BC last Saturday evening.
Here are a few notes:
We downgraded to a GV room after waiting til after 3pm for a WV with balcony. There wasn't one available, so we got $750 back and an amazing room...4606.

It was huge! Here are some pics. The porch was VERY large as well!
I got on the elevator one day with a maintenance man that had a roll of sailboat wallpaper in his hand. I commented that it was funny to see that he was going to hang that, b/c every time I see it in our room I think about it needing to be taken down.

He said he agrees and soon the whole place is going to be "redone." He didn't give details but said he has been hanging that same wallpaper the 12 yrs he has worked there. So that is interesting!
I was really looking forward to the bfast sandwich at BCM b/c I saw a pic of it somewhere on the DIS. Well, we got there and it was very thin and served on thin white bread. I could've sworn it was served on a croissant. Not the end of the world, of course, but a let down. We ate a few flatbreads there but that is it. They were pretty good. IMHO, such a big resort should have more CS options.
We only ate at HH once. The chicken sandwich was pretty good. I thought it was crazy the kids meals are $8 just b/c they come in a bucket.
There were always people checking for room keys at SAB, until 5pm. Chair and life vest hogs were out in full force. No worries...if I didn't see someone on a chair or using a life vest for awhile, I took it off their hands. There really aren't enough little kid vests, so I would bring my own PFD next time for my youngest. We really enjoyed SAB and used it a lot!
We ate at BnC once. I think I had some version of a reuben called Rachel. It was quite good! Also had the No Way Jose. Pretty sure that is as close to heaven as we can get here on earth!

We decided they need to offer a philly cheesesteak there.
We had bfast at CMC one day. It was the typical WDW bfast buffet. Nothing special. In and out quick.
I did laundry one day. Hauled it all down to the 1st floor laundry room and there was no change machine.

Went to the desk to get some, walked back, and noticed the machines were half broken. Then found a map and discovered the laundry room by the pool. Of course, there was a change machine in that one.
The 2nd to last full day we put the kids in sandcastle club. We were drop ins and they accepted us last minute. We were actually standing there at 4:30 when the opened. My DS3 cried when we left but had a wonderful time. DS5 asked the whole next day to go back. We let them go back again the next night. Both nights we wandered over to Epcot and had dinner. It was great! Expensive but well worth it. Will def be using the clubs in the future!
I didn't see Teena in the lobby the whole 10 days!?
I forgot my camera this trip

so it is a good thing we had the photopass+! Loved it! It was so nice not to see my trip from behind the camera for once. I was actually in some photos!
Did the Wishes dessert party for mother's day. My crew hardly ate anything. Good experience and lovely view but I prefer to keep my money and stand in front of the castle. I don't regret trying it.
Our arrival night was at YC due to availability issues at BC. We were greeted by name as we stepped off ME. It was lovely. My DS3 woke up the next am at 6am incoherent and burning up!

I don't know what his temp was, but he was hotter than I have ever felt. He was saying things that made no sense. I went down to GS and the manager opened the YC gift shop so I could get some motrin and powerade. They were very accomodating.
Well, those are my thoughts. Enjoy your trips and planning!
