Do you have to be 21 years old to get a hotel in Orlando, FL.? or can you be 20 years old?
MOST hotels require that you are just 18+ to check in.
only SOME hotels require you to be 21+ to check in.
to be sure you would need to call the particular hotel you want to stay at and ask what their age requirement is.
Im 18 and im allowed to get a 10 day vacation at disney world, Im only 100% positive that disney will let you be 18, sorry if i wasnt much help
