I'm in a weird situation. Last year, we relocated across the country. I used a lot of my vacation time from my previous job making that happen (interviews, house hunting, etc). Prior to that, I used vacation time primarily for travel around the holidays or for long bike weekends.

This year, I'm being forced to take ALL the vacation time I have already earned by the end of the first quarter (by the end of March). We have animals (of the farm type) so travel is out. I'm taking basically one day per week just to get stuff done around the house and plan for spring planting. I'll be doing things like tiling the bathroom counters, painting the laundry room, building tables for the greenhouse, pruning trees (though that's mostly a two person job), etc. Of course, these are all things that I really enjoy and wish I had more time to do in my regular life, so I have no problem with using up vacation time for it.
