Hosting friends and family from out of town always sounds good in theory, but it doesn’t come without its challenges. Two-thirds of Americans have told a guest to “make themselves at home” and regretted it later. That’s according to a new survey of 2,000 Americans, which found 72 percent have told a guest to make the space their own—and 91% of those have regretted it afterward.

Some of the reasons respondents have regretted allowing people to make themselves at home include guests expecting more meals than planned (54%), overstaying their welcome (45%), and making a mess (39%).

Results also looked to see who makes the worst guests, with friends (42%), siblings (39%), and in-laws (37%) topping the list. For a third of respondents (35%), the situation has become unpleasant enough that they’ve told someone they’re a “bad guest.”

On the flip side, 75% of Americans surveyed believe they’re a good host—with 31% of those saying they’re a “very good” host.

The survey also looked at the lengths that hosts go to, and the steps people can take to ensure their home is inviting. In order to be a good host, over four in 10 have purchased a new bed or new mattress for people to sleep on when they stay the night (49%) or purchased new furniture to ensure guests are comfortable (45%).
