Yes, Orlando is expensive to visit. There are ways to keep the cost down. A large part of your expense will be where you stay and if applicable access to the parks. Some will choose to go the AirBnB route which can save some money. Others choose a resort style community like Champions Gate which is in Davenport but very close to Disney and Orlando.
How expensive it is to visit Orlando also depends on your purpose to visit. Right now the more well known parks are charging very high prices. If you try Seaworld or visit Icon Park and International Drive you can spend an entertaining day or so and cut but on your expenses.
Volcano Bay is better for adults than the beaches in Disney. A little bit of investigating and you can have trip well worth the money. Thank you for asking us, Is Orlando FL expensive to visit?
