Uncle Pug:
Lamont.... you've never been married, have you.
The cost of the dive is miniscule compared to the cost of the trip... especially since you ended up paying twice as much for the travel and accomodations and your precious opportunity to dive is not really part of the official agenda. Of couse to you it
is the agenda.
Hehehe, no I don't think he's ever been married.
My wife dives. As a matter of fact she got certified before I did (and she
slays me on air comsumption. It's not fair!). But when we go on a vacation, even spefically to dive, diving is not the
only reason we go there to her. She just wants to do a few dives on top of laying out on the beach, shopping in town, etc etc etc. All I care about is the diving, and perhaps getting in a day sail or two. Oh, and doing nothing. A lot of it, in fact.
When we were in Bonaire last year, we only ended up getting in 12 or 13 dives in 6 diving days. That's about all she can handle, and she didn't really like Bonaire all that much because there's nothing to do there BUT dive (and it takes a bloody long time to get there from here; don't think I didn't hear about
that once or twice

). I could go to Bonaire every trip for the rest of my life, I think, and never get tired of it.
I think your scenario is a valid one. I know that when we go to Cozumel, I plan on doing the Cenotes on the mainland one of the days. I'm pretty sure Linda will have no interest in that, so I'll be in the exact position you outline; perhaps the dive of a lifetime, and without my built-in dive buddy.
