If you are an adult (18+), you can travel to Florida alone without any restrictions. For minors (under 18), "going alone" depends on airline and hotel policies. Most major airlines allow children aged 5–14 to fly alone through an Unaccompanied Minor (UM) program for a fee (typically $150), which includes supervision from gate to gate. Teens aged 15–17 can often fly as adults but cannot check into most Florida hotels, as the minimum age for a hotel contract is usually 21 (occasionally 18). If you are under 18 and traveling solo, you will need a notarized letter of consent from your parents for various activities and medical emergencies. From a safety perspective, Florida is a solo-traveler favorite in 2026, offering robust public transport in tourist hubs and many solo-friendly activities.
