Commissioned by Royal Caribbean International, the new questionnaire found 66% of those who use TikTok said they either have or would let the platform choose their next holiday destination for them.
The survey findings follow a recent social media trend where a viral TikTok filter generates a random destination for the user to travel to, taking the decision out of their hands.
When it comes to last-minute holidays, 46% of those feeling spontaneous agreed cruising was a good option, and 25% said they wanted to visit multiple destinations in one trip.
In fact, the current desire to "pack up and go" is so strong results showed only 6% of people would not go to a holiday destination selected at random.
The research also revealed Brits are looking to travel with their partner (47%), opt for short-haul trips (36%) and travel with children (35%).
Ben Bouldin, vice president EMEA of Royal Caribbean, said: "The trend for spontaneous travel is changing the way people book their cruise holidays with us.
"We are seeing more last-minute bookings, and the percentage of holidaymakers cruising for the first time has also increased, surpassing pre-pandemic levels."
