Up until the last few years I have not had a problem with Interval. It now appears that they never have any inventory. I have 2 weeks banked with them and cannot find anyplace to go a year in advance. Very disappointed with their service. It appears they are getting out of the exchange business and I have wasted my money extending one of my exchanges.
Recommendation: Don't bother to get a membership. It is a waste of money and time.
