I panicked when I read this thread a few days ago, as I was checking in to the PVI yesterday for the 1/2 marathon this weekend and there wasn't enough time to find a new hotel room at a decent rate. I decided we'd test our luck and if there was a problem, demand they give us a different room or we'd call the health inspector immediately.
I'm happy to say that our room (which is one of the 1-br suites with 3 queen beds) has NO sign of bugs, was very clean, and has so far been great.
I was more concerned that if we had a problem, we'd receive poor customer service, but yesterday when we came back to the room there was water leaking on the floor by the refrigerator, and maintenance came to the room immediately to fix the issue. (Housekeeping had turned down the temperature to a 1 so it was defrosting, and there was a loose gasket). They also told us if the fix didn't solve the problem, the maintenance guy was on until 11 PM and would come back and replace the fridge if necessary.
We haven't had housekeeping service yet since we've only been here 1 day, but our room was made up great with plenty of towels and the pack and play we requested already set up in the room when we got here.
None of this is to condone the response of the hotel to the OP - bad and unresponsive customer service is NEVER acceptable, and bugs in the room completely freak me out.

I just wanted to try and calm some fears if there's anyone else like me that is in a siguation where they may not be able to change their room.
(Also, as a WDW vet that's never been to
disneyland - can I just say how much I love this walk? Obviously theres other hotels right next to Park Vue I could stay at as well that would have this same advantage, so this isn't specifically a Park Vue thing. But OMG, we're paying less than we would for a moderate hotel at WDW for a 1 BR suite and the walk is shorter than the walk from the Beach Club into EPCOT - I love it!)
