Ah, this is the disconnect. It may well be correlated (a sign of whats to come), but the cause is budget slashing, not Star Wars moving. I think that's where the confusion lies. Phase 3
may not be happening due budget cuts, not for lack of space in the park.
If the budgets have been slashed, there are really only two things you can cut under our old scenario that fully preserve the priority (Star Wars). Phase 3 or the expanded boundaries and parking garages.
So your choices are:
-No phase 3, parking garages now and Star Wars Later.
-No parking garages/expanded boundaries, Star Wars now and half a phase 3 later.
Another option that clearly wouldn't be considered is to keep parking garages, phase 3, no park boundaries increased with half a Star Wars land.
If the budget has not been slashed, they can still afford to build Star Wars, expand the park boundaries for Phase 3 and build the parking garages. The change would merely be to get Star Wars opened sooner as a parking garage needs to be built before they can start on phase 3. The wetlands where
@danlb_2000 pointed out needs to be converted to surface parking before they can even start on the first parking garage.
@marni1971 can elaborate, but I still can't make sense of how Phase 3 can not 'fit' at the front. The park boundaries can be still be expanded (like they would have to be for Star Wars). Unless Phase 3 is way, way in excess of 14 acres - slightly more land can always be incorporated from parking and the layout can be tweaked to make it fit. The other way it wouldn't 'fit' is if phase 3 was an expansion to Toy Story... the cynical part of me knows the insiders would never be singing how wonderful Phase 3 is, if it were just more Toy Story.
To circumstantially answer your question, yes I'd prefer (they need) to build a phase 3 and expand the park boundaries. I'm not convinced that option is completely precluded. It's certainly a possibility, but I believe the more likely drive was to get Star Wars open, not to slash and reconfigure the budget.
