E'man,
I couldn't stay at my parent's house with my girlfriend even though we asked for separate rooms. After saying we'd stay elsewhere they offered to let me stay as long as the girlfriend slept at another location. It soured our relationship (parents and me), we only saw them for a few hours during our 2 week visit and has meant they barely know my wife. (They didn't attend our wedding either...another story) When we visit the UK again (likely in 2004) Mrs Thirdson and I will pay for a hotel room.
