A tenth house wouldn’t be back there. Not next year.
If anything, I could see a merged park like was initially planned for 2012. Now that a hard-built theater for Bill and Ted isn’t necessary, it would work fairly well.
The 2012 plan was entry through IoA. The only open islands were Port, Seuss and Continent. The front and back crossways return to the Studios where Production Central, NYC, and Hollywood were open. That was the plan. (Also, in this plan, Bill and Ted was in T2).
With so much construction in the back of the park, this structure becomes really attractive.
House locations:
SOUNDSTAGES! At least 6 can fit with queue entrances scattered at crossovers and through the bowl courtyard. They fit 5 soundstage houses in 2004.
