Hey Parrothead--
We stayed once at Riverside when it was Dixie Landings and liked it a lot as well, very peaceful and beautiful. The only problem we had was the theming, though exquisite, it was not tropical, not florida-esque. That's why we love CB!
Martinique is not that bad a place to stay, all island villages are great. My family would never stay in Matrinique, however, because of its proximity to Old Port Royale. Everything is too close and the wlak is real short. But if that is what you are looking for, then stay.
But ARUBA, specifically rooms 5256--5260 as I previously mentioned, have what we consider the absolute best views. Also, to get to the CenterTowne, you cross a wodden footbridge, walk through a peaceful island in th center of the lake with towering bamboo, parrots, caribbean steel drum music, and tropical plants and flowers and finally over another wooden bridge that crosses a nature sanctuary of flamingos, many many birds (that always eat seed out fo your hands) turtles and other aquatic animals. It is only a 7 min walk TOPS and is the most beautiful to do early morning or at night. The ligting everywhere is gorgeous and mood-setting at this Resort.
Wherever you choose, the Caribbean feel of tropical plants and laid back atmosphere is everywhere, but our personal preference for the best view and overall great time at Caribbean Beach is in Aruba, lakefront, 2nd story 52 building!!
Have a GREAT trip at Caribbean, you will love, love it!!
