I put all spending on credit cards, paying off each month, to get miles/points. Every once in a while I’ve got enough to get somewhere cool for free or near free. I’ll be heading to Europe for my second time since FIRE to spend a month bike touring. I’ll camp and be fairly frugal with food/drinks. My daily spend ends up being fairly low for an amazing trip. I’ll spend what I’d spend for a long weekend of travel if I was flying somewhere on my own dine, staying in a $100+/ nt place, and having expensive meals and drinks. Pre-FIRE I’d have done something like that, so it’s built into my spend number, but now I’m gone so much longer and having a blast.
Last year, we did a very frugal road trip. Inspired by a post I saw on MMM, I did a poor man’s “vanlife”. A Chevy Suburban with beds in the back (the link on MMM was to
https://www.suboverland.com/). I did an even trade with my existing vehicle for a 7 year old Suburban with 95K miles. Spent 6 weeks on the road. Camped every night but one. A mix of NPS, state park, BLM land, Cracker Barrel parking lots, etc. Mostly cooked on a camp stove (and Jetboil for coffee). Hit lots of great stuff (Yellowstone, Grand Teton, Rocky Mountain NP, etc.). 6 weeks was less than a beach rental.
