We went to WWOHP today and it was AMAZING!
My crowd report: Got to the park and got in line to get in at 8:30 am. I was kind of worried because there were already 5 really big lines just to get in. They opened the gates and let us in at 8:40, yay! We headed straight to HP through Dr. Seuss land, and got right in line for Ollivander's. There was already a big line, and somebody behind us said it was an hour wait. We waited maybe 45 minutes. Show was kinda lame but only because the girl that was picked didn't seem like she was really into it, so I'm sure it's better when a person who gets picked actually cares that they got picked!
So then we all were shuffled into the Owl Post, and I got my wand (and had it sent to the front of the park thanks to the tips on here!), then we left and decided to come back later and get some scarves. Noticed on the way out there was a line to get into the Owl Post.
We then headed over to do FJ, and the posted time was 30 minutes. I think we waited maybe 20 minutes, with the line moving nonstop.
There was a pretty big line at 2 of the butterbeer carts, so we got in line at a pumpkin juice cart instead that had no line and tried that first. We loved the pumpkin juice! So then we took a bunch of pictures and headed for DC. Posted wait for DC was 15 minutes, and we walked right on, literally. We left WWOHP at about 11 am.
Then we were hungry, so we went to Confiscos, and headed to Hulk after we ate. Posted wait time for Hulk was 10 minutes, and, again, we walked right on. Then headed to Dr. Doom, posted wait time was 5 minutes, we walked right on. Noticing a pattern here yet?

Then we got to Spiderman, posted wait time was 25 minutes, and we waited 25 minutes. Haha!
Headed to Jurassic Park, and we were going to do the Pteranodon Flyers and said no way when the posted wait time was 45 minutes. I'm sure we probably wouldn't have waited that long, buuuut we didn't want to wait at all for that ride. So we got in line for the Jurassic Park river boat ride, posted wait time was 10 minutes, and the ride broke down for 10 minutes so we ended up waiting 20 minutes.
Went to Lost Continent and decided to do Poseidon, and posted wait time was 45 minutes, and we waited 20 minutes.
Walked back over to WWOHP at 4 pm and got in line for FOTH, posted wait time was 45 minutes, we waited 10 minutes. Then we went and did the castle tour so we could take lots of pics. I thought there was a room with the moving staircases? We were disappointed that it wasn't there. Oh well. We then got out and got back in line do to FJ again, and posted wait time was 30 minutes, we waited about 20 minutes and that's even with the ride getting stuck once.
After that, we'd decided we had enough rides as DF had a headache and my stomach was tired of being flopped around. So went to the Three Broomsticks, no line, lots and lots of tables available. Pretty good food for theme park fast food. Oh and also got our first butterbeers with our meals in the souvenir mugs. We got one regular and one frozen and we liked them both the same. We thought the frothy topping was the best part. We rested there for a bit and then went back to the Owl Post to get our scarves (it was cold today!) and there was only about 4 people in line to get into the store, so we only waited a couple of minutes. We left and went to Honeydukes and Zonkos to make our purchases, no line to get in. Took some more pictures as it was nighttime, and left.
Overall, Hogsmeade was crowded, but I'm sure it was not nearly as bad as other days. I think it just seems more crowded than it really is because of how small and tight the area is.
Sundays seem to definitely be the best day to go, even a TM in the Owl Post said Sundays are the slowest.
We really, really, really loved WWOHP, and the only disappointment we had was we missed the Beauxbatons show and the frog chorus!
