Many years ago (like 8 years or so?), I went and just had a "meh" time. Now, a chunk of it was my fault, and I won't deny that.
It was a January trip. I love going in late Jan and Feb for the lower crowds and shorter hours. I feel like I get the "rope drop til close" experience without the lack of sleep.
Part of the issue with that specific trip was that Oregon (where I come from) was rainy and yucky, and I just needed some sun. And it was forecasted to be at least partially sunny. But, like weather does, it went from being expected to be partially sunny to overcast.... but it was too late to reschedule.
My military spouse ID expired 3 weeks before my trip, and I didn't realize it.... so I had to pay full price for my admission. Considering that I had to budget very frugally to go at all, that was an extra $$$ that I hadn't planned for.
I had planned to go do the "Walk in Walt's Footsteps" tour on my first day. On the tour, there was a family with 2 kids, one an early teen, and one maybe 8 or 9. Neither kid gave much of a care about it, so I got to listen to constantly whining kids on a tour I was paying $100 to attend. Don't get me wrong: I like kids, I enjoy kids. Heck, I worked in pediatric clinics for 20 years! Kids have good days and kids have bad days. Maybe these kids were having a bad day. Maybe they weren't really interested in the tour (which is what I really believe). But I spent 3-4 hours walking around listening to whining and bickering, and barely able to hear the guide because the kids were so disruptive. I could have stayed at home if I wanted to listen to cranky kids!
Okay, so now we have gray weather. Admission ticket issues. Bickering kids.
The hotel bed was lumpier than normal....
And I managed to forget my happy pills (anti-depressants). Missing 1 day? No biggy. Missing 2 days? Not ideal. Missing 3 or more days? The medicine has cleared my system.
Gray weather. Ticket issues. Bickering kids. Lumpier-than-normal motel mattress. And no happy medicine.
It was the only time I ever got home not planning another trip.
I recovered my happy attitude within a month or so and went back to the parks like 6-8 months later, but I'm still always slightly concerned of another rough trip like that!
