OP - I don't even know if you are bothering to come back with so much negativity being thrown at you. I, for one, deeply sympatize with you. This. Day. Sucked. I'm so sorry.
I don't get these responses. I guess you are only supposed to come to these boards to say how great DLR is, or something. Until this thread I had been super-thrilled with the lack of OP-bashing on this board compared to what goes on over on the WDW pages.
Why say she should spend have spent more days there? Or that she had unrealistic expectations?
OP NEVER said she expected to do everything at both parks. And they only wanted to use one day of the vacation for park touring. (There are a lot of other things to do in CA!) They had a list of 10-12 attractions as the goal, and they were willing to hoof it back-and-forth to see them. The only "problem" with the plan was that stuff kept breaking down.
If I only had one day to spend at DLR (whether by choice or necessity) I, too, would have a specific list of what I wanted to see. For folks to suggest that she could still have had a nice day by doing other attractions is like me saying you should go watch a basketball game when you wanted to go to a football game.
We canned our WDW trip for this past May because I wasn't willing to risk not getting on our favorite rides as FP+ was not looking too inviting to us off-site folks. For me Disney IS rides and attractions. I'm not going to say, "Well, at least I watched that street performer," or "Well, at least that muffin was good." No. If I don't get into or onto the attractions that I care for, it's not a good day at Disney.
OP - I get your regret. That was a boatload of money to shell out to not get to do your rides. I do wonder why you left mid-day. (Was your mother or daughter tired?) I'm sorry it stunk and I don't blame you for not wanting to risk it again.
I've been to WDW at dozen (?) times as an adult, and I've only ever had to content with TT being closed. If it happened more frequently on my visits, I certainly would have had less visits over all. Broken rides annoy me. I don't drink the Kool-Aid and IMO if a ride is prone to closure, shut it down for as long as it takes to fix it properly.
I hope the rest of your trip rocked. And I do hope you can write a great, factual account of your day and send it to DLR. I do think it will fall on deaf ears, but at least you will have seen the complaint through to completion.
