If you want something really close by, the Paradise Resort Hotel is right next door, and Emerald Reef Suites is close by as well. A few blocks down is the Mayan Princess, like Paradise Villas and Emerald Reef a condotel (rates at Mayan Princess are usually great off season). A little farther south at the edge of town there is a cluster of condotels including The Palms and Belizean Reef Suites. If you'd rather go north a little bit The Tides is a great value in a hotel, and there's also the Seven Seas, a condo/timeshare.
But you could take a taxi and move most anywhere (except North Ambergris) in a few minutes for around US$5, as it's only about 3 miles to the most distant hotel to the south.
