I think that sounds like a wonderful idea! A party that starts at 6 actually makes a lot of sense - the parents can go out to dinner or do something with their other kids. You made your party at an appropriate time for the ages involved - even though it was "late night".
IMO, A party that doesn't start until 8 doesn't even make sense for slightly older kids (heck, I wouldn't even want to go!). The parents probably have other kids to get in bed as well and are possibly ready to be in their pajamas themselves. If it's on a Friday, everyone was up early. I'm guessing many of the guest would have fallen asleep on the car ride there!
We had a sheet for everyone to put their cel phone or other contact number on before they left in case there were any problems. I had also put on the invitations that kids could be picked up before we showed the movie if parents wanted to. For DD5's party a couple of parents showed up early and watched the video with their child. It was a late night and we did do them on a Saturday and not a Friday... my kids are exhausted by Friday night.

The 7 year old doesn't even start getting ready for bed before 10 p.m. I don't agree with it but its her lifestyle. 
My ds who is 6 wants to have a birthday there and I said, it will never happen. I may take you and friend but being responsible for a big group of young kids and rushing through everything is not fun. We just did Chuck E Cheese last weekend (before that it was last June) to celebrate DS who is 3 being potty trained. Anyway I'm of no help but I agree with you.
