Accommodations in Lake Havasu for the Boat Show/Desert Storm week gets tight very quickly. I've heard that the Nautical Beachfront Resort is sold out which isn't a surprise. If you're still looking, try the London Bridge Resort, the Heat, or the Islander -- all three near the hub of the activity. Or you can go to the Boat Show website,
http://www.lakehavasuboatshow.com and click on "Do/Eat/Stay" for a list of hotels and motels in the immediate area. You might also want to consider renting a house for the week which might be more economical -- most major real estate agents in town (Keller Williams, Coldwell Banker, REMax Properties, etc.) all deal in short term rentals. Guaranteed, it's worth the trip!
