There've been several posts about Advanced Open Water (AOW) so I'm just replying to my post above where I suggested perhaps just having the OP's son do AOW since then they'd get 5 more dives with an instructor and also get the AOW cert perhaps for a similar price. As has been discussed on many forum threads here, the "Advanced" part of AOW is really unfortunate and people should not get hung up on that, as : (1) AOW does not make one an advanced diver, and it probably should be really called Open Water Part 2 or similar; and (2) yes, it's certainly possible for divers with "only" an OW cert to be advanced divers -- experience certainly advances skills for most.Also, as an alternative to a private DM, you may consider going ahead and getting his AOW while you are there if they'll allow you to tag along with them. That gets him 5 dives with a DM also, and may be a cost effective alternative to just paying for dives and a private DM -- plus he'd have the AOW cert (seems more and more dive ops in the U.S. are requiring AOW for many dives). After the 5 AOW dives you can decide whether you want a private DM for the rest of your trip or not. I'll add a plug for Tres Pelicanos (small fast boats, and great dive op overall) and their DM Jose is really patient and calming with inexperienced divers (and great at finding cool little critters too).
So, if you think of AOW as merely Open Water Part 2, then it still can be handy for a new diver to get 5 more dives with an instructor and practice the 2 required dives (for PADI, that's Underwater Navigation and Deep [which is anything over 60 feet]) and 3 elective dives -- most new divers probably would benefit from Peak Performance Buoyancy, perhaps Night Diving [really easy and fun in Cozumel] and whatever else is of interest (Fish ID, Underwater Photography, Wreck, etc.). Again, there's nothing really "advanced" about it, these are just either things that are rushed a bit in many OW classes or nice little add-ons under instructor supervision.
The fact that more and more dive operations (especially U.S.) are starting to require AOW certs for many dives that are not especially difficult dives makes AOW a handy cert to have in the U.S. But again, I think the main reason these are requiring AOW is that so many OW classes these days are a bit lax, so having AOW at least shows you've had a bit more than the bare minimum instruction.
And I know there are many older divers here, and some stellar instructors here, who had/have very comprehensive OW classes, but from what I've seen most OW divers (and many AOW divers) could benefit from more dives with an instructor as soon as possible. So, my initial recommendation for the OP still stands: if you're going to pay for a Dive Pro to dive with your son anyhow, I'd consider getting his AOW cert rather than just doing a private Dive Master -- just think of AOW as Open Water Part 2.
