Re:Nautilus
As long as you understand the hotel is only a 2 star, you will be OK. If you are expecting anything above that, you will be greatly disapointed. We were in PV last May, we stayed at the Decameron, but had to use the Nautilus for our SCUBA lessons as they have the dive pool. We found the hotel very dirty, old, falling apart, and the dive pool was discusting. We were there in the afternoons and we only saw 4 people around the pool. I think alot of the Mexican people use this hotel for their holidays now. So, if this is what you are looking for, then have a great trip.
