Lots of things to do in Aruba:
There are watersports booths all along the beach if you want to snorkel, dive, windsurf, boating, deep sea fishing etc. If you have your own snorkel gear there are many places that you can go and snorkel on your own. Malmok Beach and Arashi Beach and along this area are the spots to snorkel. A lot of people also go to Baby Beach at the other end of the island to snorkel.
All the beaches in Aruba are public. You will find many spots along the beaches with huts and you can use these and take some beach towels etc.
The casinos are located in all the major hotels: Westin, Radisson, Hyatt, Marriott and downtown in Oranjestad, The Crystal and Seaport Casinos. They are open til the early hours of the morning. The stores in Oranjestad are closed on Sundays. The grocery stores are open on Sunday, but only half a day. We have a small grocery store across from Wacamaya, called Ting Wei. It is open Mon-Sat from 8 - 9 and on Sundays until 6pm only.
