Having credentials in the tourism industry will definitely be advantageous for you.
Properties are constantly looking for qualified management/trainers. Your past industry related work experience will also affect your ability to find suitable employment and get a work permit.
Belize is growing exponentially and likewise the tourism industry here. With a small labour pool, more foreigners are being employed here than ever before.
My advice is to broadcast your resume to numerous resort properties. If you are offered a position, allow the resort to file for your working papers (make this a condition of employment). It is not a difficult process if the proper procedures are taken.
I moved down in 88' and again in 95' while in my mid twenties. You can make good money here and save good money here, some choose to spend good money here also (like I used to do). It's all up to you!
Hope your goals are reached in Belize!
