Marriott Opens First Resort in Belize The eco-luxury development will be the first-ever Marriott International property in the country. Marriott welcomed its first property in Belize last week, with the boutique resort Alaia Belize, Autograph Collection. Situated in the historic town of San Pedro, the eco-luxury development spans over 20 acres and sits on more than 1,000 feet of beachfront access. On the island of Ambergris Caye, it can be reached via Philip Goldson International Airport in Belize City by taking a 15-minute flight to San Pedro Airport. Alaia Belize features 155 guest rooms and suites, ranging from studios to three bedrooms. The rooms offer an average of 1,200 square feet indoors and almost 900 square feet in open air, per unit.
