Mine also finished at 10.30 and was a Sunday wedding.

Our guests appreciated the fact that it was early so they didn't feel bad about leaving early as even for those that had to travel they were still home at a decent hour.

FWIW - you don't need to specify an end time on the invites the way the evening pans out things just happen to end. We did our "leaving thing" at 10.20pm but the cab was late so we sat and hid in a special room all our guests were gone by 10.50 and the venue was fine with that.
