the regular room has 2 queen beds and generally a day bed - the studio has 1 queen bed and a double (full) sleeper sofa. the BCV is also new just opened in July.
But remember what Doc said. They accomodate 4 people ( or 4 plus one child under 3). So if it you, your spouse and three kiddos, one kiddo will have to be under 3.
Last week we stayed friday night in a room at the BC we didn't have enough points to stay friday at BCV were we had stayed Sunday-Thursday. We had a 2bdrm at BCV but we toured the model in room 108 to check out the size of the studio for future trips. The studio is bigger than the regular room at BC plus you get fridge and microwave plus free use of the laundry room always an important item for my D.W. The BC rooms are nice but you can tell they are over a decade old. The one advantage is the daybed which in our case helped but it was a little crowded. You really can't go wrong because no where else in the world has Storm A-Long Bay. Enjoy!
