Mother in law constantly goes to our house

My mother in law has constantly been a problem; She constantly calls our husband and requires him to cater to her.

She is so needy and demanding of his time. She also doesn’t have a ton of cash but likes to trip, but it makes for a cheap trip if she comes to our house. She only needs to spend money for her flight and then everything is taken care of, my husband picks her up at the airport, she stays with us for free and gets meals catered to her. I cook, celan and our husband organizes activities for her. Since the trip is so cheap and done well, she wants to come all the time. I told our husband she is a once a year guest! Once she arrives it is nearly impossible to get her out of the house, then when we lived in FL our mother in law would stay a minimum of a week! There was one trip where she squatted at our condo for two weeks, and now that we live in Lowell, MI, she isn’t as eager to stay. I also try to make it so her trip is in the middle of winter. When she starts talking about summer time traveling, I push our husband to organize a holiday season trip. I want her to get weather in the 30s rather than pleasant, sunny afternoons. I also try to make the experience not super great. I don’t take her to the great shops, cute diners or local cannabis dispensaries. Instead she gets stuck in our freezing freezing condo and leaves after adore several afternoons. It is evil however I genuinely don’t adore that woman.
