I recently went to Texas. It took me about 10 hours each way.
I wore my Attends, a body suit (onesie), and shorts while driving.
I changed once at a rest stop each way.
I slept in my body suit and on a bed pad and found it easier to wet at night than at home.
I wore a pullup during the day.
I used a total of 10 diapers in 4 days (3 nights).
Anyone else travel diapered?
