I didn't bring underwear on a trip one time. I've never been on vacay, so I hope my little trip qualifies.

Forgot passport and didn't realize until I was at the airport :(

Summer vacation with cold and rainy weather the whole time.

Mixed up the time change from west coast to east coast -- had to leave our Broadway musical splurge early to make our flight home!

This past summer my fiance, daughter, and I went to Disney World. We decided to make it an experience and drive themail 2800 round trip. Better yet, I should say my 6 and half month pregnant self, drove the whole way. Between not finding any place to stay during a 6 hour road closure except for a place that made Bates Motel look like a 5 star hotel because you cant even see straight let alone function any longer after 18 hours of sitting in a car & only being halfway to your destination, pushing through hurricane rain where if it wasn't for the hazard lights of fellow cars we all would be in a ditch, a daughter who gets heat exhaustion, forgetting 2 important suitcases & coming home to a bill from Disney stating you owe almost $400 for international calls that we never even made. Gladly we made it home alive & managed to have an amazing time along the way and not going into early labor from all the stress & mishaps is a plus

We went to beach vacation and realized I forgot to bring sunscreen and goggles. We had to buy new one.

On my honeymoon our room was infested with bed bugs. We left 3 days early without a refund.

I fell in a fish hatchery of trout when I was younger and my daddy had to reach in and grab me. It ruined my whole vacation and I did not want to do anything but sit in the cabin. I also had a bad bike wreck while looking and eyeing a boy and flipped on the concrete pavement and had to be rushed to the ER. I had to get a shot and pain meds from being all banged up. Lesson learned to never ride a bike looking at a boy when the pavement is wet :)

the weather prep when I am packing is always my mistake - no matter how much i think I'm packed properly i am always too cold/too hot/no raincoat packed/wrong shoes/etc

Our last long trip was when our youngest of 4 was a baby. 6 months old. We had everything. Or so we thought. I thought we had every essential item we would need to travel on the road and camp for 2 weeks. We drive 700 miles over night to get to stop one to find...oops. Everything but a bed for the baby. No bouncer, or pack and play..We forgot it! How? But we had all 4 kids and ourselves and enough supplies strapped to the roof of our van, we would have been ok Rio be gone a month. But. No baby bed. But we had the bottom drawer of a wide stable dersser @ the cabin we were at. I pulled it out, lined it with blankets add layed her in. That was a mistake. She woke up in a new place in a pulled out drawer and screamed! She never slept in her own crib by the time we made it home since. She sleeps with us now. Poor babe.

When Dad decided to take us to St. George for the first time, I thought it would be a blast! It was. That is, it was until the drive home. Turns out too much "fun in the sun" can lead to a miserable and barf filled ride home. I was stuck in the back middle seat of the car, squished between my younger siblings (both too young to be out of their booster seats) as they puked the whole six and half hours home. Yikes!

My husband is a notorious over- planner! Last year he overbooked both us and our friends (and their kids) on our vacation together and in turn everyone was ridiculously cranky and overly exhausted. To add insult to injury, I left my anxiety meds at my in-laws' snowbird house 90 minutes away, my son was constipated and my daughter had diarrhea. Two kids with stomach issues, two other kids with attitude issues, their parents begrudgingly reprimanding them for being insulting to their friend and me having a panic attack at the most magical place on earth? Nope. This year we decided to take a trip two weeks before they were available to join us and I made it clear to my husband - this is over my birthday week. We will all have moments to take a deep breath and relax!

We forgot to pack condoms and I ended up pregnant. LOVE my daughter, but oopsie! lol

Trying to plan something to do every single minute, with not much relaxation. Not a good idea.

I have an over packing issue. Laundry can always be done. I just learned that, the hard way.
