I voted 50-99k due to having company provided home leave in business class, up to a certain budget amount that was 1 trip per year, but increased by the same amount that the kids' international school fees had cost until they graduated from HS. Kids are now off to university, so we use some of our home leave allowance to go see them, and some to go to our California home. Also, when we find a round-the-world fare that is the same price as going home to Cali, we will go to Cali first, then continue on to London or Paris before winding our way back to Tokyo. It would be pretty typical for us to burn about $5-6k each major trip (5 so far and 1 to go), not counting the airfare. Hotel and rental car total about 3k, and the rest is restaurants, DW's gifts for her Japanese friends, and admittedly perhaps not "real" vacation expense, we spend on things we cannot so easily find in Japan (I just bought 2 pair of running shoes in Hawaii, for example, along with some elder Tang - Metamucil, ibuprofen, Tylenol, running shorts and shirt for DW, and a business suit for me). A short weekend jaunt to Hong Kong might only set us back 1500 or so, plus the tax on the FF miles tickets.
This kind of spending cannot survive for us into retirement. We both know that, so we always try to piggy back a trip for DW via the round the world scheme or on FF miles when I have to go to a "new to her" location for my business, tag on a couple days or a weekend at the end, and cross another trip off the bucket list.
For our FIRE budget, we are looking at 12000 per year plus another 4-12k for RV depreciation, insurance and maintenance, plus an extra 3000 for the gas to power it. The 4-12k range is simply because we don't know if we will get a trailer or an RV, so up to 27k in retirement.
