Yep. You'll like Amigos. Pro 48 boat for the long trips, great people. Nobody else runs a boat that nice. Continental breakfast on the rides out, great lunches, experienced and knowledgeable DM's, decent gear, if you need to rent. Oh, and great people--did I mention that?
Do the Blue Hole so you can say you did, like a bunch of the rest of us. Or skip it and just do a bunch of close-in reef dives. The BH is a lot bigger deal before than after your dive. The Turneffe trips are very nice and I'd recommend at least one of them.
Tell Marciano that "Dad" from Nebraska says hi and we (the whole family) will see him soon. And I do trust them with my family (daughters ages 12 & 14 dove with them last year and our son, 8, had a ball snorkeling with the local kids who went along). I wouldn't say that about just any shop and get a lot more particular when the kids are along.
