Most likely it is a certificate for a 1-week stay and can only be booked within 60-days. Most resorts within the 60-day window have "upgrade" fees from $300-$3,000 for the week. We got one of those a year ago. We could even sell it for $25. One of the resorts what Alhambra in Poinciana FL. I could get a 1BR for horrible weeks for about $300 most of the time. If I booked directly through someone else, I could get it for $300 - $400 also. We looked at many other places and it was the same garbage.
If they are offering a "resort certificate", say no. Get it in writing first that you can get Wyndham Bonnet Creek for a 1-week stay.
