You cannot beat Honolulu. There is plenty of service, you can ride the bus to the Waikiki hotel district for $2, hotels are plentiful, many under $100 per night. There are a zillion bars and restaurants, all within walking distance. Best of all, you use the same money, there are no customs inspections, you can read and speak the language, and it does not cost you $100 in customs fees and departure taxes. Oh, did I mention perfect weather and girls in bikinis?
