I'm in the minority of making whatever park we pick for the day an all-day park. Our last trip, DHS was because we have to be there early for the FP for TSMM, then stay till the end for Fantasmic. We still missed on things too (B&B & IJSS - no good times, Idol & LMA - no interest). I'll probably include DHS in our potential 2015 trip since we'll be there around Christmas, and the Osborne lights are worth a look (right?).
But I totally agree with a lot of the ideas for development. Replace LM with a Frozen show. Replace B&B with a Princess revue spotlighting princesses without a "better" attraction (Tiana, Rapunzel, Sleeping Beauty, etc). Update TGMR with some more recent movies.
Then go all in on some improved areas. Star Wars Land - obviously! Extend Pixar Place with something for Incredibles and/or Wreck-It Ralph AND re-theme the HISTK play area to Wall-E. (I'm specifically leaving out Monsters Inc since there is already a ride in DL and the MILF at MK. My best option would be to move MILF to DHS and put in something else new at MK, but I digress.) And a Villains/Halloween "land" would be my ultimate wish for DHS. Something along the lines of PhilharMagic, but utilizing all the Villains. Maybe a Nightmare Before Christmas Ride?
I have no issues with the rumored closings (save for IJ... could it be moved?), but hope that it could mean something new comes in the empty space instead of just empty real estate (EC). DHS is full of possibility and it's unfortunate the lack of love it gets. Maybe the Frozen Summer can increase the funds and recognition of park needs?
