Communities use hotel taxes to fund themselves off the visitors. I’ve heard of high VAT / sales taxes in Europe but not in less developed countries . In Europe they are included in the price. We are supporting the Cozumel economy with our dollars. After paying a fortune to fly to Coz, experiencing all these various Cozumel taxes and fees , and the airport shuttle boss selling me tickets then claiming not enough passengers so I’d have to either buy all the seats or pay a $25 taxi to drive ten minutes, forcing us to leave the airport to get a $10 taxi, I’m ready to go to Honduras and dive Roatan for similar diving at lower prices. Or to Asia for much lower prices. I don’t know that a budget Cozumel dive vacation is possible.
