Flying to Belize is high $$$ compared to most places....We did look into flying into Cancun and taking the bus to Belize....I didn't want this to be a 2 week trip...want to send that time in Europe in the Fall...Yes, Belize is more expensive than other areas...but if you are a diver....it's just one of the top 5 places for diving....so you got to look at it that way...Cheapest way is to fly into Cancan....take bus to Belize...spend the night...take a ferry boat to Ambergris Caye....this is all easy to find over the internet..
You can find discounts if you look for them...
Happy Diving...
All the Best,
Ruth
