This is our first time staying in a club concierge category and we are very excited about it, we're not arriving til Thanksgiving, just had a few ?'s.
Mostly the bottled water I've seen is in glass bottles. Others may have different experiences, but we always bring water in plastic bottles for the parks/poolside. The glass bottles are more for your room.
Every day there is different hot offerings, and more than just scallops. At BC, we saw samosas, cold lobster salad (I know, not an option), fried dumplings, cheese is always out, veggies with dip are always out, rolls and crackers, peanut butter/jelly, sliced apples, a salad of some kind (like olives with feta, tomato/basil/mozerella). That was during out very short recent stay at BC, other items we've seen items like mini pizza, eggrolls with assorted fillings. They are mostly fried dumplings of some kind, but only one at a time is seafood.
That said, you can ask about allergies, and they may give you an alternative. they might also plate up some items that have not been contaminated. The procedures vary from resort to resort, and CM to CM. In my experience, if you ask them to plate something though you are kind of committing to being there at a certain time. That's the downside.
We seriously don't mind 'standard view' club level. The view you get is not going to be ideal, but you usually get some kind of partial view. Usually views of actual parking lots are obstructed with landscaping, IME. No matter where you stay, Club level almost always has at least some view of a rooftop- you are on the top level of the resort- it's impossible to avoid. (at all WDW resorts!) On our most recent stay, we had garden view. It was only slightly different from standard view in my opinion. Both times we could see the courtyard, and other guest rooms. The only resorts that are sort of different is the CR Bay Lake view on the 12th floor and the AKL safari view. I suppose if you get Poly or GF castle view (non club level) that's also sort of different, but at GF you can only get true castle view on non club level. (there's always a building in the way)
Our standard view CL rooms have always had balconies, except once at Poly. I think at BC it's only the deluxe rooms that may have standing balconies. I would never pick those because they are also not on the same floor as the lounge/desk. My personal opinion, is that the most important 'request' of staying club level is to be close to the lounge. I don't nkow about your vacation, but we don't spend all that much time on our balcony, maybe 20 min each morning tops. Almost any view gives me a sense of being at WDW, in the heart of the magic, but having to go between floors or walk down a very LONG hallway is very time consuming.
I'm thinking you have a slightly unrealistic idea of what club level view means. Fireworks view probably likely in suites at BC, otherwise it's luck of the draw. At BC, club level rooms face all different ways, some will have a view towards Epcot, some don't. (consider looking at Google mpas to see the resort layout to see what I mean) When we stayed Standard there, we would have had a fairly decent view of the fireworks if we had been there during the show. Last we as well, our Garden view room would have had about as good a view as you can get. But I will warn you, the Epcot fireworks are very low to the ground, there are large trees between Epcot and BC, so you are never going to get a full view of the show from any balcony. At best, you'll see about 2/3 the show. I've only been at BC twice, but I have stayed at the Swan many times- which has a bettter angle and is higher- and even there, you don't see the whole show. If you really want a view of nightly fireworks, from your room, with minimal trees, and no parking lot, on club level - the ONLY option is Poly MK view. Everything else is going to involve some compromise. Even at Poly, the view is not that same as in the park.
I think King beds are an option. go tot he Disney website and check the descriptions of each room category. It will tell you there.
I'm not trying to be mean, I love club level. I am guessing that you will LOVE it. Of all the CL resorts we've tried, BC's staff is among the very best! The pool is amazing! Be sure to explore all the nooks and crannies of the pool area! Also, if you have kids, get a kids meal at the outdoor lunch area so they get a sand pail. The food is excellent, the landscaping is among the best, and the location is fabulous.
