If it's the same you need to be very careful, Brian. The seller may be trying to use one good listing to suck people in and then actually convey to you something that's just a little different. For example, you think you bought a gold week. They slip "silver" into the contract or something. Or you think you got a 2BR and suddenly the paperwork says 1BR.
Just be careful. Make sure you read everything carefully. And use a credit card so if they steal your money you at least have a shot at getting it back through a dispute.
