Honeymoon gift basket wedding present?

A couple of friends of mine are getting married soon, and I need to get them a present, so I'm making them a honeymoon basket. They're going to New York, Venice and the Bahamas, so any ideas what I could put in it (necessities, travel guides, that sort of thing)?
--------------------
suntan oil, travel guides, map, journal, stamps for postcards, gift cards for things they may need like rental cars, etc. , beach towels. If you like silly things, put in 2 apples ( new york is the big apple) a book on pasta dishes ( venice) and flip flops or a recipe for the drink " sex on the beach" for the Bahamas. :)
