The following are the all inclusive options available from MR:
CasaMagna Marriott Cancún Resort, CasaMagna Marriott Puerto Vallarta Resort & Spa, Curacao Marriott Beach Resort & Emerald Casino
Los Suenos Marriott Ocean & Golf Resort, Frenchman’s Reef & Morning Star Marriott Beach Resort, St. Kitts Marriott Resort & Royal Beach Casino, Grand Cayman Marriott Beach Resort
I go to a different one each year. This time it is the Casa Magna Cancun, 3/13-3/20/2011. (ought to be interesting during spring break) !
My ranking so far is (based on logistical friendliness for a family of 4 2 adults/2 teenage boys)
There were various nuances involved with the other 5 that I did not care for (Transportation issues in Los Suenos, availability of activities in St Kitts, lack of activities (other than shopping in Puerto Vallarta), although pretty to look at, Frenchmans Reef pales in comparison to any Florida beach regarding enjoyment of beack activities.
As stated above, trying out Cancun this trip and will do Curacao next year.
Go to Marriott rewards header, use points, then choose a package (Airmiles/hotel/rental car certificate). All inclusive options will be 70k - 90 k points extra depending on LOS. You will need to call MArriott number to get travel package reward. You can book hotel with MR rep, then arrange airline travel (can change hotel arrangements wit MR rep if air travel schedule conflicts), have up to 1 year to use hotel reward, and can book inlcusive at anytime prior to trip if you need to save up points.
All in all, I have found these packages to be a great deal. With the Delta 60K miles promotion the travel package miles, and about 60K annual business travel miles, we basically can go anywhere in the world for a week. (50K-60Kmiles per ticket)
The all inclusive option (should you decide to partake) limits you to the above 7 locations (for now).
