We plan on largely following the lead of our dive master. However, should we be requesting anything? We are diving 5 days (2/day) and not planning on leaving the AC area (not going to the Blue Hole, etc.). I hear Hol Chan and shark ray alley are definitely something to do even though they can get crowded. We are staying at X'tan Ha so we will ride kayak out to Mexico Rock.
With 5 days, I hope we don't end up just going to close places unless they really are the best. For example, since we are already 7 miles north of town, are there any great dives up north (even farther up from X'tan Ha? Also, the dive shop might want to only go to the place up north with Hol Chan being the farthest south. Is that OK? Are there a ton of great dive sites along the reef or are there particular spots that are clearly destinations to plan to see?
