good questions!
having fun? yes indeed. and found old friends staying two doors down the hall from us. Which is stranger than you'd think given we're not from this part of the world.
Taller than the mouse? No. He is a giant among rodents!
Crowds? Heavy, especially in tomorrow land, which we are now referring to as neverland, as in never go in there (ok except for star tours /space Fp). The crowds, new lines, and stroller parking have made it very hard to get around.
Also - be prepared to queue for a Fp for Splash and GRR. GRR has quite a long return line too - think it's because of the late FP issues. But at 3pm today there were fifty or more people lined up in the walkway area. Splash yesterday had about that many queueing for FP machines at that time.
Two more days, weather great, little mermaid fun, GCH great.
Using Lines app - not all that accurate FWIW - but worth a try.
