On that trip I've been whining about for a while now.
I'm happy I joined and it's been good so far, but I'm not happy with how many of the things I was told we'd do got turned into "I never said that", we're rushing and only aiming for a tourist trap (rather than stopping at other interesting locations along the way. While I've got nothing against the end goal of the trip, I had hoped to get to see/do some other things as well) and the knowledge that I'll miss out on nature at it's most beautiful in favor of something that could never even hope to compare to it really annoys me.
Oh, and I tried to post a rant similar-ish to this yesterday, but the site gave up before I could post it. Grr and stuff.
