Building 3 and 4 will be closer to the buffet and pool. Building 5 (our favorite) still close but a bit quieter.
Do be aware of the sales "sharks" (time share sales) a simple no will do. Don't let them tell you that you "have been assigned a time for your "required" tour. This is total BS. You are not required to tour anything.
You will be assigned probably 1 restaurant with a 4 day stay. You can change (not always possible) and sign up for other nights at the desk at 9am in the morning. We have almost always been able to change and most times also get other nights rather than the buffet. The buffet food has slipped a bit in the last year but will ok. Best restaurant available to you in my opinion is the steak house.
Have a great trip and remember the "stupid" price you paid on CC for your trip. You will have a great time.
