A good place to stay overnight with your parents-in-law

We don't really like going on trips even with our own family.

My cousins and I used to gather, but due to the outbreak of COVID-19, we haven't been able to meet for almost four years.

The problem is that next year is my mother-in-law's 70th birthday, and I don't know what to do..

Is there a place within the country you enjoyed traveling to, even if it wasn't an extravagant overseas trip?

A one-night or two-night, three-day stay is also good.

Please recommend a good value-for-money travel course if you've been on one^^
