Planning a trip to Ambergris Caye to dive a couple of days (probably 2 days of 2 tank dives) and then going back to the mainland to rent a car and do some of the other activities, probably ATM cave and some ruins. We are newer divers (15 dives) with 2 teenagers (15 & 17), so we stick to shallow dives of 60 or less. Thinking the reefs and shark/ray alley by the cayes would be good for this and then head back to the mainland for the other. So, my question to those with experience in Belize, would you go in March (spring break) or June (summer vacation). I can go either time, but was just trying to see if one would have big advantages over the other. Also, open to any other thoughts, advice or suggestions. Thanks in advance.
