The phone number for bottled water company: Agua Riviera Nayarit
Garrafones de agua.
Best to stay with brand name companies Epura, Ciel and Bonafont to name a few.
There has been reports of bootleg bottle water.
Local home delivery can be spotty, unless the stop includes many clients.
Good luck and have a great vacation
Does this group have more comprehensive info than these TA forums? Thanks
