We stayed at the Timothy Beach Resort on St Kitts. Our review is posted. If arriving by cruise ship tour the Island 3 hours $75 US. A good tour may take 41/2 hours if you stop an view the Botancic gardens and the Old Fort, so expect to pay aroun $110 US. WE used a driver named Gloria. She spoke very clear english and had very pleasant dispostio Cel [-].
Also consider Nevis is 45 minutes by boat with freqquent departures aprox $25 US return.
The train is promoted on cruise ships probably because they get a cut on the ticket sales and don't get any portion of a taxi fare. The train departs from Airport and proceeds up the east side of the Island.The cost is very high and the secenery over the east side is nowhere near as nice as the more developed west side. Better to hire a cab and tour the west more beautiful side of the Island. Arrange for 2 couples to share a cab. If you wanted to see all the island including the south end close to Nevis will likely cost $140 but would be a solid 6 hour trip with many stops. Compare to train I thibnk around $75 per person and the cab tour is a bargain.
Whitehouse Beach with sunken wreck close to shore is good for Snorkling $20 US for taxi each way. Watch out for the rash and searing sting from the slimy coral, better access the water from the small sandy portion.
Nice intimate meal at the Beach House restaurant has only been opended since April/08. The Taxi will cost $25 US each way to there south end of Island location. The meal most expensive is Lobster of course with pre drink, decent wine from good wine list and desert around $175 but a very memorable night. Great attentive service great food prep, clean and good view over the water to lights of Nevis. A great way to celebrate an anniversay or engagement.
