If you plan on travel for peak season, do not purchase with the hopes of something coming up. Seems inventory is not the way it use to be and there are less units coming up. I know I have had a hard time trying to get something that would work for me this summer.
As a matter of fact, I was just going to post an update on what was going on with me trying to get a unit. I finally gave up. I went on Priceline and got the Clarion Uninversal Orlando for $35 per night. I am going to Universal Aug 8th and the only thing coming up was Celebration World which is 15 miles away. With the price of gas, it is not worth it. I would not be able to take a mid day break from the parks. I did a unit that was far from Universal in June and it did not work out. It cost me over $25 every 3 days in gas just to and from the park once a day.
I have two certificates left. I am going to keep one since it is activated and use it in Sept (will have to play with my days at work). There are lots of units then. The other certificate, I am going to get a refund on. I work for the school district and cannot ask for an entire week off during the school year. All my long school breaks are during peak season & it just doesn't work for me.
Like I said, if you have to travel peak season, do not get it with the hopes something will open up. However, if you can go off season, these are a great deal.
