We thought we were lucky one night doing BTM five times in a row, although dh had to come off after two, (it was the last night that those who had only been taken on to work the summer holidays were working). I think it is the best way ever to watch the fireworks, as we had done three times before at the end of the night - lucky dd does not need much sleep when we are at DLP and we stay until closing time most nights, especially when just the two of us go.
