Absolutely a terrible excursion. Princess should not support this in their materials. The animals, fish, sharks, etc are in horrible conditions with small tanks, some having NO rocks or structures to hid within. Just nasty and overpriced. The ferry over to the bus/taxi area is TERRIBLE!!! Just packed in like animals - no one counts to see if there are too many. Just sickening.
Aruba is awesome. Just gorgeous. Great shopping, very clean and felt safe. We took the Mi Dushi sailing ship cruise/snorkle and it's worth every penny. We snorkled three sites, had a great lunch catered in and an open bar with actual liquor in the drinks. I loved Aruba.
