Anguilla is accessible by air and sea.

By air: There is an airport located on Anguilla. Because St. Martin/Maarten is so close, you can also fly into the Dutch side of St. Martin/Maarten and take the ferry over to Anguilla. Do expect at least one layover unless you are flying in from the east coast

By sea: Ferries depart every 30 minutes from the French side of neighboring St. Martin/Maarten. The ferry ride takes about 20 minutes and costs $15 each way ($12 for the trip and $3 for the departure tax). 

Customs and Immigration: Each visitor is allowed to bring in one bottle of spirits duty free. (wink, wink).

Dates of travel: Jerry and Judy will be there from June 28 to July 6

The wedding party will be there from June 30 to July 4/5

You can stay however long you want.

*update 3/13/2005 - Many airlines occasionally will have sales running from destinations within the US to St. Maarten. For instance, AA currently has a sale that ends May 25 so it won't work for this one, but keep your eyes peeled open for future sales.
