Assuming that you are referring to Tropica, that and Banyan Bay aren't really comparable, except that they are close to each other on Mar de Tumbo beach. Banyan Bay has big, beautiful, 1000 square foot two-bedroom, two-bath condos, with full kitchens, living area, jacuzzis in the master bath. Tropica has attractive but certainly not overly large hotel rooms. You could probably fit four Tropica rooms inside a Banyan Bay apartment.
Of course, the prices reflect the difference.
