Is it necessary to exchange money for Aruba or can you get along fine with a credit card and American $.?

Question

Also does anyone recommend any great areas to dive in Aruba?

Answer 1

Pelican Adventures Aruba is a good company to dive with if you want to go with a company. otherwise maybe the locals can recommend places to dive on your own.

No need to exchange your $$, widely accepted all over.

Have a great trip)

Answer 2

Virtually all commerce in the tourist areas, with the exception of the grocery stores is done in U.S. dollars.  I wouldn't bother with exchanging dollars for florans.  Sorry, I can't help with the diving part of your question.
