I was down in Costa Rica this summer, went to the same place my wife and I went to a few years ago. We chatted with the same beach chair-umbrella lady, she was upbeat at first but the 2nd day when we mentioned the lack of tourists she said it was down at least 50%
Sounds like people just don’t have money for vacations. Not when your spare pennies have to go for groceries. Probably taking in more local attractions, day trips, etc.
