I'll be going on a cruise in October from New York to San Juan. We will be porting at St. Thomas, Antigua, and St Lucia. Are the cigars on the ship worth buying? Are the cigars on the islands worth buying? I am planning on bringing my own, but need to know if they are worth making a purchase. this way I will know how big of a travel humidor I'll need to bring with me.

Any other comments or suggestions about cigars on the cruise ship and the ports along the way would be grateful.
