I'm planning a trip for my family of 4 (2 adults/2 teens)during their Christmas holiday. Will it be difficult to get around or find meals on Christmas Eve and/or Christmas Day in San Cristobal? Our experience has been that in some areas of the world, everything closes down on holidays as people spend time with family. We understand this but it can be tough as an outsider. Any thoughts? We could move the dates by a few days.
