The biggest problem with Monster's INC is that it is in DCA not DL. DCA is a horrible little park. Visited it for the first time last week and had a miserable time. I visit a lot of theme parks and this was tied with the worst theme park experience ever.
Park was at capacity but have the food service places were closed. The ones that were open were doing a horrible job. Placed an order at one and then went to pick up our food. It took 22 minutes (this is AFTER we placed our order) to get a tray of cold dry burgers. I have on a few occasion had food as bad at other theme parks, but never had to wait so long to get it. And we had similar experiences at each food place we visited at DCA.
Rides had horrible lines but the staff was sending ride vehicles out half empty, they didn't seem to know how to keep the lines moving. Line jumping was everywhere and the park staff was ignoring it, or in some cases aiding it (dropping chains so that large family groups could join up with the one member who had cut ahead in line five minutes earlier).
I felt it was terribly managed, the staff was untrained, I saw lots of staff standing around not sure what to do. (I will not use the term Cast Member, as the level of performance I witnessed doesn't deserve the title).
I didn't think that that attractions were all that bad. California Screaming was a fun ride and the Alladin show was amazing. But the management of the park lead to long longs, bad service etc. which tended to make the crowd a bit nasty.
I hadn't been to DL in years and I was horrified, I thought that they had wrecked
Disneyland. We got fedup with DCA and just wanted to get out of there, we went over to DL and it was as good as ever. At DL they have Cast Members, folks who know there job and are well managed. Food we fast, efficient and delicious. CMs monitored lines to keep line jumping to a minimum, lines were flowing smoothing and the crowd was generally having a good time. It was a world of difference.
