Missing Exit Stamp from EU
As I prepare for my trip to Thailand/Cambodia/Singapore - I was looking at my passport and realized I had the following stamps from my honeymoon:
Croatia Entry via Airport
Slovenia Entry via Land
Croatia Exit via Airport
I never realized that we did not get exit stamps - I believe we were just waived through after showing our USA passports.
On my trip to Thailand, we will be stopping in Vienna for 14 hours and Frankfurt for 6 on the way home (and plan on leaving the airports). Will I have any issues missing this exit stamp?
