Road trips for families is how you stay on a budget. It’s easy to get hotels for around $100 a night that include breakfast if you stay out of world-renowned destinations.
A lot of vacations also involve crashing at another family member or friends spare bedroom/fold out couch.
I grew up with family vacations like this (inflation adjusted) and I had a great time. It’s hard to wrap your mind around when you think vacations require significant travel.
