Just so happens that I sent our friends a travel checklist. Some of this won't apply to you since your staying at a hotel but I'll leave it in since it might help others

28 days till we go!!

------------

Gear:

1. Dive Computers: If your computer has a replaceable battery, buy a brand new batteries and bring the tool to open it. If it is rechargable, check to make sure the charge holds. My batteries on the Shearwater were shot - with the servicing, I have yet to charge them and it's been over a month.

2. Transmitters: Buy a pair of replacement batteries and have then on standby. Check your gear, but I think this is probably what goes in all transmitters: Amazon.com . Also, remember, tramsmitters are triggered when you turn on your tank - so leave tank OFF until dive time.

3. In your save a dive kit, I recommend having these items:

a. Adjustable crescent wrench with flat ends: https://a.co/d/gIkPGFr
b. an extra mask strap
c. an extra fin strap
d. a coin that can open the transmitter
e. Zip ties
f. batteries for transmitter
e. spare mouthpiece
f. defog - baby shampoo

4. I do carry a Nautilus GPS rescue beacon that will transmit distress signals to the coast guard and all other boats on every dive, so no issues if we were to all get swept out as long as we stayed together.

5. I travel with my own battery operated smoke and C02 detector, so no need to bring one yourselves.

7. Bring a few laundry pods - the apartment comes with washer and drier.

8. Powder drink mixes, gum, jolly ranchers for post dive.

Pre-dive drip equipment tests and tips:

1. Check regulator and hoses. make sure they are not damaged or leaking. Put your gear together and put it in the water. Look for bubbles at 1st stage, 2nd stages, pressure gauge, power inflator and and along the hose lines. Check for 1st stage leaks on the boat - listen for it @ 1st stage. those tank get alot of use and o-rings blow often.

2. Blow up the BC past max capacity and make sure the over-inflate valve does its job and the BC bag is strong. Also check the power inflator buttons to make sure they are not "sticking". If they are, try a little WD40, and if that didnt work, replace the BC hose.

3. In Cozumel, you won't need anything more than a 1.5 mil heater top. Cant speak for others, but that is all I will have with me. Wife uses a skin and maybe a 1.5 top over it.

4. Bring head covering on each dive to keep head from burning while we wait for the boat.

5. Bring a dry bag for the boat and a hardcase drybox "wallet size" for money, DL/C card, etc.

7. Bring a few recyclable or plastic grocery sacks - the Mega/Chedrui do not use them anymore

8. Dive flashlights - be sure you have a powerful flashlight - I carry an Orcatorch D550 and they are great even on day dives. The Orcatorch D710V is attached to my go-pro and the wide beam really brings out the colors.

9. Other things to consider to have with you:
a. whistle on BC
b. rattle or tank banger
c. safety sausages
d. sinus meds
e. Mesh bags with each persons gear - ours roll
f. reef safe sunscreen
e. I bring a long sleeved sunshirt / hoody for every scuba day
f. Bring a snorkel for the chance we might do that somewhere like money bar or elsewhere
g. Ear beer: 50% alcohol 50% vinegar

10. Things you will not need - leave at home:
a. gloves
b. hood
c. knife
d. reel

11. Packing: How we pack:
a. Large suitcase: 2 BCs, 4 boots, 4 fins, 2 wetsuits, my toiletaries
b. Large suitcase 2: The queens royal supplies
c. Carry on 1: my clothes, 2 regulators, PCs and go-pro
d. Carry on 2: 2 rolling duffles
 
Thanks for this detailed write-up. This trip will just be me, wife is staying home with the kid and the dogs. Nice to know about American as thats who I'm flying with. Electronics - can you tell me what outlets they have? 120 US or different? I know I can google it.
If you can get your hands on a small power strip, take it if you have multiple electronic gadgets to charge. We have batteries for cameras, dive computers, flashlights, and iPads/iPhones. They have some outlets but they aren't in the most convenient of places. One side of the bed doesn't have any outlets. This is an experience I learned from.
 
Do bring your SMB and reel - and practice using it. Cozumel is drift diving and if you get separated from your group and need to surface you’ll need a surface marker.

EDIT: the list keeps growing … :cool:

I do not have a reel but have been browsing amazon for one and will be taking one. Probably wont have a realistic chance to practice using it however.

I'm not trying to be nit-picky about words, but for this type of recreational diving I prefer a finger spool over a reel. Spools are simpler, cheaper, lighter and smaller for stowing. I tend to think of reels as more common in technical diving or for towing dive floats, though some people do use reels for DSMBs.

As for practicing, not always easy to find time to practice (quarries are good for that), but here's my favorite video on the subject:
