We just booked a trip with Suzy at the Dive Bus, and we are anxious to get diving again in two weeks. The diving looks good in Curacao, but prices seem to be a lot higher than other Carribean destinations.
It is all about cost of living. Some islands are poorer than others and it is reflected in the price of tourism. Curacao is not a poor island so things are going to cost more there. Places like Dominican Republic is a lot cheaper but a 5-star resort on DR is going to be a 3-star resort on Curacao. Additionally, the equipment you'll find at The Dive Bus is really nice, fairly new and well maintained.
