Hi,
I know you will have a great time in Cayman. I use to live there for 6 months. I hope I can help. There are quite a few dive operations on the island. Most are about the same price and most are very good. Treasure Island has their own dive operation. I have never dove with them but they had a good reputation when I was there. It may be very convenient for you since they are on site. My favorite dive operation is the one at Sunset House. It may or may not be as convenient for you. They are located south of town. They may pick you up at the hotel. The beach diving there is awsom. If you love tunnels dive Devils Grotto. It is a beach dive located just south of town, you dive out of the Eden Rock dive center. Not much coral or fish but it is fun to swim through the tunnesl.
Stingray city is a MUST. Be sure you go to the right one, for divers. There is also a shallow Stingray City. Only 3 feet deep and for snorkeling.
The north end has very dramatic walls so you do need to be experienced. Along seven mile beach (which is only 5.5 miles) is where most of the dives are done. Lots of wrecks! I love the Balboa.
Treasure Island is great. Right in the middle of everything if you like night life. You can just walk around. It is very safe.
Yes, it can be very expensive. Check to see if your room has a fridge. If you like to drink, that is what will add up. A few years ago the gov. imposed a liquor tax which almost doubled the price of drinks. Like any place if you eat at all the tourist, fancy places it will cost you. If you are budgeting there is always ways around it. They have the Burgerking, Pizza Hut and Subway. Not as romantic but it helps to cut back. Ask the dive crew about places to eat. I could give you more suggestions but I am traveling and don't have my Cayman stuff with me.
There is no bartering in Cayman. What you see is what you pay. Prices go up on days when the Cruise ships are in. Keep in mind that almost everything is closed on Sundays. Even the tourist stores. Caymanians are very religious. Do not wear bikini top and shorts shopping, although the folks from the cruise ships do it on occasion the locals are offended.
A day drive around the island is fun, not alot to see. The Turtle Farm is fun.
When are you going? If you want more information I can get it to you when I return, Sunday.
Take care,
Kristy
