Here's a fun thing to do.

Google a bunch of hotels and resorts and look up a bunch on TripAdvisor. This will prime your re-targeting pump and you'll get to see a lot of digital ads for these folks and people like them. Cubes, leaderboards - the works.

You're going to see fairly quickly that they look pretty much alike. Especially the resorts - a beach-in-the-foreground-water-in-the-background shot with some line that, frankly, is probably pretty much interchangeable with any other line on any other ad. In other words, nothing terribly unique or compelling here folks, move along. It appears that nobody ever even thought, for example, to show the beach from the water - if for no other reason, just to look different enough to attract attention.

Lookalike advertising is a waste of money. The purpose of advertising is to grab some eyeballs to your message. Not look like everybody else.
