I think it should be logged, specifically how much weight you use, type and size of tank, what protective gear you wear, kick count per 20/25 yards. It is important to keep this data, as one of this day, you will find yourself diving the same configuration, and can not remember what weight you need. You should also do a good buoyancy check once your tank is down to 500 psi, and trim excess weight until you are just slightly negative with this near empty tank.
In training, your instructor would not count it toward your log. As I understand it, some dive organization defines a dive as a significant learning experience, so some pool dive might qualify. But most instructors, I believe, would not count it as a real dive for qualification purpose.
If a resort require a "real dive" within a year, you might be lucky and pass this one. It might be better just to sign up for a refresher dive with a DM (in the pool), that will likely count as a skill dive to satisfy most resorts. I think most dive shop will give you a sticker for your C-card or log book to show you pass your skill tests. One local LDS charged only $25, a give away price, for a refresher course. You meet with an instructor for an hour or two going over the OW test, then spend about 45 minutes in a pool. I think most charge 3 to 4 times as much, you might want to do that just to be sure. It might be good to get a really experienced diver to go over your skills with you. I think the skills are listed in the PADI OW book, and as long as they are performed in shallow water, you really can't kill yourself doing them.
Fortunately, or unfortunately, most dive resort in Mexico doesn't give a hoot about your dive log, they only want your C card. As rusty as you might be, you should demand that your dive boat does not take you to deep sites or sites with strong currents. Add heavy waves to the mix, you could be in over your head, literally.
