Have you ever considered a Royal Holiday timeshare package? I am doing some work with Royal Holiday and they just added 12 new destinations - in Cancun, Utah, Texas, Canda, and Dominican Republic; also expanded to Brazil. They have been around for 25 years and have over 67k members.
If you have any questions about Royal Holiday let me know, I'd be glad to get some information for you...and either way, enjoy your vacations.
