You will absolutely love BWI concierge! The CMs are amazing, the resort is beautiful, and the location is perfect. All of the rooms have balconies, but some balconies are smaller than others. Even the small balconies that the Deluxe Concierge rooms have are big enough for two people.
The food offerings are great:
Breakfast: donuts, pastries, muffins, toast, fruit, coffee, tea
Midday Snacks: dips, hummus, popcorn, pretzels, bottled water, Coke, Diet Coke, Sprite
Afternoon Tea: tea, tea sandwiches
Wine and Cheese: hot appetizers, huge cheese and crudite platters, 2 whites, 2 reds, White Zinfidel
Desserts and Cordials: delicious desserts (tarts, tiramisu, etc.), any type of cordial you can imagine
You can request a room with an Epcot view to watch Illuminations. If so, you will not have a BoardWalk view. The balcony on the concierge lounge provides beautiful viewing of Illuminations. The rooms are located on a restricted 4th floor (though some are also on the 3rd). You must use your keycard to gain access. If you look at the outside of the BWI, the rooms are over Spoodles, BoardWalk Bakery and Flying Fish.
Any other questions, let me now! You'll have a wonderful time!
