Tnkrbell,
You can bring your own drinks! We even asked if it was ok one time and they said sure. The only thing you will be missing out on is the late night cordials, but if you really want something, pick it up on your way back to the room. I will say one thing~if you stay Sugar loaf~do NOT take a 2nd floor room over the service entrance. They start banging LOUD at 5:00 a.m. bringing carts in and out of the building. Needless to say, in off season I am NOT up at 5:00 a.m.. I would ask for a Dormer room. The food offerings were really good when we were there, lots of veggies, chicken, seafood, fruit, cookies, finger sandwiches, etc.. I have heard that they are the same food wise as the Main Building, just no Cordials in the evening.
As for if it is worth it..........tough call. It is really nice, convenient and you really feel pampered. If you are looking at spending more time in the resort, then it might be worth it. If you are like us, you kinda come and go. After all, Downtown Disney and Pleasure Island are open late.

The plain Lagoon View rooms are very quiet with GREAT Views and after all there are sooooo many GREAT places to eat there, you could eat anywhere with saving that $$$$ per night difference.
Let me know if I can answer anything else.
