Pixie Hollow seems to still have the 60 to 90 min waits all day during the day from what I've been reading on here. If someone has seen different, please chime in. Most people seem to be saying that the best time to hit it is at opening. Now Toontown doesn't open until 10AM with the MK usually opening at 9AM, but most people sound like they are going pretty much there by 9:30 and milling around til the cue opens up. If you are there right when the cue opens you can get in with a short wait. From what the people who are there right at opening are saying, by the time they are done with their meet and greet, the line is already up to 60 min.
As far as the fairies are concerned, when I was there, I met Tink (of course), Iridessa, and Rosetta.
