I can relate to that stupid, foolish feeling of thinking you've lost something at WDW, only to learn later that you hadn't.
On my first night of a 10 day trip in July of 2013, I made my way over from Saratoga Springs to Downtown Disney for what I thought would be dinner & a couple drinks before an early night in bed to charge up for the fun ahead.
Well 5 hours later, after stops at Lava Lounge, Paradiso 37, Raglan Road, & Kook's Sports Bar (across the street @ Buena Vista Palace), I finally got back to my room around 1:30AM.
Fast forward to 11 AM the next morning.
In addition to my well-deserved hangover, I had the sickening surprise of seeing one of my credit cards wasn't in my wallet.
It was strange because I had used a different card & cash during the entire evening out. But I figured I must have gotten it out and then changed my mind about using it, and left it on the counter.
So instead of soaking up the joy of my first full day in the "World", I had to get on the phone and start calling all those places I'd visited the night before.
No luck at all.
Although I found it interesting how many cards are constantly left behind by morons like me. One of the places had 12 forgotten cards from the night before, but none with my name on it.
So of course I then had to call and cancel the card & hope it hadn't ended up in dishonest hands.
I was totally disgusted with myself.
About an hour later I was going through all the brochures/paperwork I had been given & collected during check-in, and that stupid credit card fell out onto the floor.
Definitely a relief, but made me feel like a complete idiot.
Oh well.
Despite the rough start, it still ended up being one of the best WDW trips I've ever taken. Hopefully I've learned a lesson and it won't happen again, but we'll see.
