Sorry you didn't have as good a time as you would have liked!
I can relate...there have been a couple of visits out of the more than 100 that we've made to DL that weren't "great", although the vast majority have been fine.
Matterhorn is pretty bumpy, I'll give you that (although it DOES seem a bit less so in recent years, unless I'm hallucinating? Anyone?) I guess it takes growing up on it to develop a nostalgia for it that makes one disregard the bumpiness.
I have to sympathize with you about rude CM's, too. Before a few years ago, we had NEVER encountered rude CM's at DL, but the last few visits each have been worse than the last in that respect. In fact, it's one of the main reasons I'm not even going to bother to go this year. I love DL, but I'm burnt out for now on grouchy CM's. They definitely have a way of tarnishing the trip, that's for sure.
I am really surprised to see anyone write that DL is dirty, though. I really hope the cleanliness of the place is not taking a downturn! I've always thought of the park as exceptionally clean myself, and I'm somewhat OCD-ish about germs, ect., so for
me to think of it as clean it has to be pretty darn clean, lol. i've only once encountered a messy restroom, and it wasn't horrible. Sometimes the outdoor tables at the buzz lightyear restaurant (sorry, can't remember the name at the moment) are kind of grubby from the last customers who sat there, but other than that, I've not encountered dirtiness (is that a word?) at any of the restaurants. I'm always surprised in fact, at how clean the walkways are, considering the volume of people. Ugh, PLEASE don't let DL be getting dirty!! if THAT happens, I will likely stop going. As it is, the rude CM's have me halfway out the door. Which is sad to me, because I grew up not far from DL and have spent my whole life going there, and taking my children often as well. It's been a home away from home for us our whole lives, and I hate that there have been a couple of times in recent years that I've regretted spending the money to go.
DH wants to go to WDW instead next May, and after hours of comparing the two online, WDW seems not nearly as enticing to me as DL. I love going to DL and knowing every nook and cranny like the back of my hand, being able to get from one place to another quickly, walking between parks, etc. I have NO desire to visit somewhere as sprawling as WDW seems to be. I love being able to jump off one ride and run to the one right next to it, lol...I don't want to have to waste any more time between rides than I have to! Plus, I love California Adventure.
Although, the lure of more pleasant CM's is tempting, I'll admit.
The castle has never been anything I really cared all that much about one way or another, so I don't mind that it is smaller. I don't necessarily think of bigger as being better though, but that's just me. I'm sure my kids would freak over the huge castle at WDW.
Sorry DL didn't live up to your expectations! I say if WDW does it for you, then stick with it! It's no fun feeling like money and/or time have been wasted, that's for sure.
