The ad begins with a shot of Denise Van Outen in a swimming costume and getting out of a pool. She says "there are places you can go to have fun, like this..." while gesturing to her surroundings.
Her monologue continues "...and stay in places like this," as she walks through a nightclub, cycles through a forest, strolls through a cabin and, finally, drives a power boat.
The 30-second ad is by agency Red C Marketing and produced by Mob films, with media buying handled by All Response Media.
The ad will run across ITV1, Channel4 and Channel 5 and be supported by digital and print activity.
Geoff Cowley, managing director, Hoseasons Group, said: "We wanted to show the huge variety of holiday experiences which is available under the Hoseasons brand.
"Denise van Outen has a very high profile with our target market, and we are delighted that she agreed to front the campaign.
"Our return to television shows a commitment to driving forward the Hoseasons brand and its continued recognition in the marketplace."
The campaign runs until 20 February.
Last year, Hoseasons partnered with Sport England to create the Go Active brand as part of the Government's Change4Life scheme. It launched a range of travel products encouraging children from less wealthy backgrounds to be active.
