We've never stayed a Casa Mexicana but have talked to several folks that have during Carnaval. They really liked it. They said the hotel sets up food and drinks on the pool terrace for the guests so they can enjoy while the parade moves by. CM is in a good spot to see all the action on the ground. They also said their breakfast buffet was very good as well. As far as the noise, not sure. You might be able to hear some of the street festivities at ngt but I think except for the last ngt of Carnaval most of the ngt time stuff will be over by 11pm. My guess, not fact.
I can't speak for Vista del Mar but alot of folks really like the place and their staff.
We'll be there that week, staying at the Fiesta Americana. A all time favorite of mine.
Good Dives, SeaFlea.
