I can also thoroughly recommend Mexico. Chris, Danny and Fred at Zero Gravity are awesome and my best ever dives were out there. I have been lucky to have experienced some fantastic Ocean Dives, including Prince of Wales and Repulse and some ridiculously remote islands in the middle of the Pacific that no-one had ever dived before. Parker's Tunnel in No Hoch is better than any of them and is less than 10m deep.

Cave 1 in Mexico - Lanny's Trip Report
I am in a state of incredulous anticipation at the moment as I have managed to get approval to have our honeymoon in Mexico. Currently negotiating on the number of dive days!
