We have owned a cabin for mamybyears, maybe 10 years. It is 5,5 hours driving from home. It is onl6 doable because we don't have kids back in the car. We often try to visit for a long weekend, but have also visited for normal weekends. Now we are working 80% and have many long weekends.
I think we spend 30 days a year there, on average. Often a visit every month, and a part of the summer vacation.
I hope you can also have your cabin cheaply. Ours has electricitity, which costs a lot to just have access to. Usage costs only 10% of the initial cost to have it. If you have water, you need to keep the cabin free of frost the whole winter, and therefore warm it up, which is extra cost. We have no water and let it be cold the whole year. When we go there in the winter, we sit close to the oven, until the cabin is warm from wood firing.
We have also been so fortunate that the cabin community has put a property tax on our cabin, for very unreasonable percentages. As we live in another community we don't have the option to vote against it. And the loney will be used for all local stuff that cabin owners don't benefit from. The tax is now 20% of the yearly expenses for the cabin.
Our cabin has depreciated. The neighbouring cabin has recently be sold for the same price that we paid for our cabin many years ago. And the neighbour's is much bigger than hours. So I can guess what ours is worth. I think we list about 30% of the value.
Before we owned this cabin, we would typically hire a company cabin a couple of times a year (typically in the winterly half year) abd otherwise camp.
As you (OP) has 4 children, owning your own cabin might be pretty convenient, compared to camping. When the children grow older, they might typically want to travel elsewhere in the vacations. That you can sell it. But until that time, if you can spend some of your vacations at your own cabin that you already pay for, you can save quite a lot compared to hiring something else.
