I've stayed Marriott, Holiday Inn, Explorers, Dream Castle and Radison.
I love Marriott, so much I bought a week. a 1000 sq ft home with 3 tvs, 3 toilets, DVD player, stereo, sleeps 6, great pool, activities, and spa for the price of a room in the Hotel New York - amazing.
I sometimes stay at Holiday Inn because it is free often for me as a corporate traveller. I hated the Explorers.
