Worlds in Hawaii is obserd. If it is going to be outside of the coastal US it might as well be out of the country period. Hawaii is a complettely stupid location, heck any Island is a stupid location (no offence Japan). When it's on an island everyone other that the locals have to fly in where as if it was in Europe, Asis, North America, or South America a lot of people would be able to drive in. I mean come on everything in Hawaii is outrageously priced. A customer where I worked who is from Hawaii said a 2 liter of Coca Cola cost $4 I mean that's at least 2.5x the price it is in the continental US. I checked on travelocity for a five day trip to Hawaii from Vegas and Berlin, Germany from Vegas and the cheapest hotel in Germany was only $250 or so dollars more which would probably be the money you would save on food and gas while there. Let's face it Vegas is an ideal location, people from around the world come hear on a regular basis all the time. There are quit a few hotels that are still kid friendly (Circus Circus, New York New York, and the Excalibur) plus at least then there are actually things for the parents to do and there are plenty of things for the older players to do (since lets face it, the oldest age group is and will probably always be the largest).
With all the things that POP has done recently (6 foreign card limit, banning drawn on and signed cards, Worlds in Hawaii again, making another set of marked sleeves, major rules changes the day of Worlds again) I can't see this game lasting much longer and I really hope it doesn't if they are going to continue to do things like this on a regular basis.
