This is certainly one of the better Marriott resorts. I heard a story that Marriott took over management of the property before it was opened...it may have originally been built as another resort, which would explain the very un-Marriott look of the place.
Compared to the other chain resorts in Aruba, I would head back to the Marriott. The casino is one of the most popular in Aruba--we stood in line at peak times waiting for seats at a blackjak table!
