---- On the entry paperwork you fill out Aruba wants to know where you are staying. Don't think they want people just back packing it around the country for weeks. In about 20 trips to the island never been asked anything about $$$$$.
And getting off a cruise ship there is no Aruban Offical checking you over. Just your cruise card through the ship's computer gets you on the island.
