I am a recent owner to GL at Vidanta. I just got a call from Vida Lifestyle which is ICE which also owns SFX. They are selling me to upgrade to a "Ultra" package. The portion of the package that is intriguing is the expanded reservation window. That is I can deposit a week and then book another week at Vidanta years ahead. So this gets around the limitation of the 12 month window for GL, and other hotel limitations (e.g. 6 months for GM). As I do resell un-used weeks this would be very valuable to me. Any insight or advice as I do love Vidanta but don't trust anyone close to them.
