Ah, well, that's great. I thought I saw something about wireless access at the clinic, but couldn't remember where since I was just reading over my wife's shoulder. You may want to get that info posted at the clinic (near the computers would be a good place) since the receptionist had no idea what I was asking.
One other item to bring with your laptop computer is a wireless adapter if it isn't built in. Hotel Lucerna has free broadband, but it's wireless G. They don't document this on their website. They do, however, have a few loaner wireless adapters but I wouldn't plan on using one. The coverage is decent, but would've been a little more reliable with a higher gain antenna.
We have Vonage (woo hoo. woo hoo hoo.), so I brought our telephone adapter with us from home so we could call everyone back in the states (or Canada, Mexico, Europe, etc.) completely free of charge. Unfortunately, there wasn't an ethernet port in the room so it rendered that useless. However, I ran down to the Plaza Rio, bought a computer headset from the Steren store, and activated the Vonage Softphone feature so that we could place and receive phone calls through the laptop. We had virtually unlimited calls for $10.
Had I known for sure about the wireless access at the clinic, we could have called directly from the clinic. :-)
Be sure to check with your cellphone carrier to see what the rates are for international roaming and long distance. T-Mobile said it would cost .80 for roaming and .20 for long distance to the states from Mexico.
I would also suggest bringing a small electric kettle and your own chicken broth cubes. The hotel's chicken consomme is good, but some people in our group said it was different at night than it was at noon. It's certainly not expensive, but the $6 for broth, jello, and bottled water can add up pretty quickly.
Regarding the Gas-X, please note that it works on intestinal gas only. It will not help with any leftover carbon dioxide from laproscopic surgery.
