Another vote here for Days Suites Maingate East. We were there in Nov. 2002 and will probably return there this November. The suites are very spacious. The property is right next to Old Town which is a great entertainment complex with rides, shops and restaurants.
If you just want a plain hotel room, the EconoLodge Maingate Hawaiian is also good. We've stayed there 2 or 3 times. But for the price, its tough to beat the Days Suites.
