GRAND TURK: This is a small island and there is a nice beach close to the port. There is a place called "Jacks Shack" where there are free beach chairs and reasonably priced drinks/food. There is also the cutest dog Topher that was so fun to watch digging in the sand and greeting everyone. There are also a couple of climbing inflatables that we paid 10pp to swim out to and play on all day. The water was clear enough to snorkel and warm enough for comfortable swimming. Good time for cheap!
LA ROMANA (Dominican Republic): We arranged in advance for a day pass at DREAMS all inclusive resort. The email for reservations is firstname.lastname@example.org. We had chairs, towels, food, drink all day for $60 adult/$30 kids. If you have a large group, they do give group discounts. Food and drinks were good, however the water was not suitable for snorkeling and there was quite a bit of vegetation floating in the water. Taxi there was $15pp round trip but we had to negotiate that. Getting on the taxi was chaotic, it helps alot if you have someone in your group that speaks Spanish.
CURACAO: This was my second time there and it was beautiful. The floating bridge is a must see. We didnt dock until 2pm so we were limited on what we could do. Most of the businesses (except bars and restaurants) close up at 5 or 6pm. We took a taxi from the port the the SEA Aquarium $20 for all three of us one way and $21 adult/$11 child admission. So for all three of us it was about $100 total and a GREAT value compared to what Carnival charges. The aquarium was AWESOME. Not crowded and we got to feed sharks, turtles, stingrays. There is also a sea lion and dolphin show that were very good. There was a tour with great guides that educated us on the wild life. Lots of hands on fun. HIGHLY Recommend this! They also offer swimming with the dolphins at different price levels. Will do that next time. On the way back to the port, we walked across the floating bridge and then took the free ferry back. There are shops close to the bridge if you get there before 6. Great day, not a big expense.
ARUBA: We grabbed a taxi $20/family one way at the port and went to Palm Beach. The beaches there are public and there were free chairs. There are nice bars, restaurants, restrooms, showers on the beach. We did a ride on Big Mabel (like tubing on an inflatable couch) for $15.00 pp for 15 minutes. That was alot of fun.
