Hi and congratulations. You picked a wonderful spot for your honeymoon.
CSS is a wonderful place and very quiet, so it really won't matter which building you are in, especially if you are able to get a third floor room.
Please know that while Couples trys to accomadate all room requests, they do not accept any prior to when you get there. The rooms are assigned the same day as your arrival.
If when you booked, they were offering a $100 spa credit then you will get that as well. And of course if you are staying for 6 or more nights then you get a his/her massage as well.
Before you criticize someone, walk a mile in their shoes. If they get mad, you will be a mile away and they will be barefoot!
