I think they had to put the brakes on with all the projects going on. Between the design and construction teams being stretched, the vendors being overwhelmed and trying to figure out what is going into the new location and what timeline it will be on, it has to be a little overwhelming for everyone involved.
I'd guess that with the end of construction in sight for Volcano Bay we may things start to ramp up with the next round of projects. Right now the logistics of materials/labor/etc. alone all around the property must be a nightmare for the teams in charge. I'll be they are looking forward to the closure of WnW in December so they can really utilize the space there for things like parking all the construction workers.
