Mostly I watch from Main St. If you get an adr for crystal palace for about 45 minutes before the start of wishes, you can walk out at the end of your meal just in time for wishes to start.
The last time (Jan 2006... too long) we were there the kids (17 and 12) wanted to go on space mountain at the last minute, so I watched from outside of the exit of space mtn, it wasn't bad, but main street is better.
