So you booked just the room only and not an all inclusive stay?
The $279 quoted (and paid for? in full?) is for the week not per night?
Perhaps you should place a phone call to Couples and ask them if they have your reservation and if so for them to send it to you.
Then you can compare between the two and this would give you a better understanding of what you have purchased and what Couples will honor.
Also welcome to FT and please do not feel discouraged by the previous posts we really are a warm and fuzzy bunch. I believe that the previous posts were as much sarcasim as anything else.
