Hello everyone,
57 yr. old male, traveling solo. First time headed to Cozumel, Yucatan and south along the coast (mid Jan/2018 for approx. 2 weeks). Had a few questions:
1) WEATHER: what can I expect for typical weather (night and day) for this time of year?
2) CLOTHING: was going to bring a pair of jeans, swim shorts, hat, tennis shoes, some t-shirts, beach sandals and a very light light jacket.
3) PERSONAL: I'm fair skinned so I will be bringing lotion of course. sunglasses, needed medicines, personal hygiene stuff, etc. anything I'm forgetting. (yes, I have my passport)?
4) ELECTRONICS: I'll have my cell phone with me....is electric in Mexico 120v/60hz. (in other words...does our stuff plug in down there?)?
Is there sell phone service back to USA or is that between me and my provider (Verizon)?
5) DIVING: I most likely will be traveling alone so what do you guys recommend for my personal belongings while diving (wallet, passport, phone, etc.) ?
6) MONEY $: should I exchange for some peso's before leaving the states? I figure on traveling with small US $ also as most international places like this and helps for bartering, etc.
Does anyone recommend buying some type of "travel credit card" that has a predetermined amount issued to the card so if it is lost it would only be for this amount?
7) WATER & FOOD: of course, I've heard the horror stories about the water and plan on drinking a lot of bottled water. What about beverages (soft drinks, alcohol, etc.)...anything to worry about there? Any foods to definitely avoid that commonly cause digestive issues due to the water, etc.?
8) HEALTH / MEDICAL: my insurance says I'm covered but the $ reimbursement figures might be a little different compared to USA costs. Any hospitals, doctors, etc. that I should avoid, etc.?
Everyone please feel free to chime in with any suggestions.....especially if I haven't covered it.
Thanks.
Jontay
If you want to bring jeans, I would wear it onto the plane. I would also bring a pair of synthetic, quick dry pants that will launder easily in sinks and dry quickly if you need to wash it or if they get wet. They're great for travel and keep dirty laundry smells away longer than cottons and natural fabrics, especially denim. They also release wrinkles nicely and you can even get a dressier pair if you want!

Ditto synthetic shirts instead of cotton. Don't forget to bring mosquito spray - I highly recommend picaridin 20%. It's as effective as DEET 30%+ and isn't as gnarly.
For your cell phone, there is service in Mexico but you will likely pay some exorbitant roaming charges for data, voice, and text unless you have a specified plan with them. Call them to ask before you leave. Some have flat rate access days (unlimited access for a flat rate per day and days you access are the only ones that are billed). Others are a per text, per minute, or per kb charge which gets expensive quickly. Find out before you go. For me, I generally turn on airplane mode and just have wifi on the whole time I'm there...I use AT&T's wifi calling and am connected to wifi most of the time so I can text and call back to the US, browse web, check e-mails, etc. for free. You can also use WhatsApp and Facebook messenger, or WeChat...so many platforms. In an emergency, I could turn on and use like a regular phone. Alternatively, if your phone is unlocked, you can get a local SIM card and get a local number with data and not worry about any of that. You'll be limited to what you pre-pay for, but you can re-load it and can easily budget how much you spend based on how much you're loading. When you run out, just re-load.
I like to keep my passport in the hotel safe. I don't bring it out on the boat with me. I just carry a copy of it in a dry bag. I would exchange some money before your departure that's enough to get you going. You may choose to go to an ATM once you arrive for a slightly better rate, but I usually find that it's not worth the hassle. I'm not sure if it's the same but a few years ago, many standalone ATMs, even at Cancun airport, had card skimmers on them....Courtesy of a mobster group. So don't get cash from the airport in Cancun in that manner. Things may have changed. I used Santander bank when I was there and an ATM at a large grocery store, also Santander, and it was fine.
Is this your first time traveling out of the country or to Mexico? If so, see if you can get a standing antibiotic prescription from your doctor in case your tummy doesn't agree with the local bacteria. Bring Imodium, and any other over the counter medications that you think you might need. There's nothing like not feeling well in another country and having to hunt down medications...You already have it if you're prepared.

Brush your teeth with bottled water and drink alcohol or packaged drinks. If there's ice in your drink at the resort, ensure that it's filtered water - you'll know if there's a hole in the ice cube.
For medical, ensure that you have coverage while traveling overseas and if not, buy supplemental travel medical insurance. I like GeoBlue - I buy $0 deductible up to $1M and for Mexico for 10 days in my early 30's it was less then $35 or something. It's 100% coverage including pre-existing conditions and is part of Blue Shield/Blue Crross.
