While diving in Cozumel, I suffered from decompression sickness. I was forced to spend an extra two nights in Cozumel. I was staying in the southern resort zone, but to extend my stay was going to be too expensive (and too far away from where I was receiving treatment). So, I decided to move in town. I found Hotel Plaza Cozumel on the internet at an excellent nightly rate (perhaps because it was the low season) and booked it. I had a secondary issue in that I needed to drop off my bags and my brother's bags before going to get treatment the day I was to check in. At the same time, we needed to be able to get my brother's bags back from the hotel so he could fly out as scheduled. All of this before check in time. I wrote the hotel and email and got a very quick response that they would have my room ready at 8:00am (6 or 7 hours before check in time) and my brother could leave his bags at the front desk. With so much to arrange and coordinate in rescheduling my trip and getting treatment, it was wonderful how easy and quickly this hotel solved one of my obstacles for me.
The staff was always friendly and helpful. They have a strange procedure where you leave your key at the front desk when you leave the room, but it never presented any problem for me, so I was okay with it. They serve a pretty good better-than-continental breakfast.
The room is basic, but clean with a lot of television channels (which was necessary since I was on bed rest). My only complaint is that the beds are pretty hard. Several days stuck in bed took its toil.
I would definitely consider this hotel in the future.
