We have only been once before, we arrived on the saturday and just really looked for the smallest queue, we only managed the teacups ride that day. The next day we met up with my friend who has been there every year and we sort of took up their tradition of going on POC first.
However this year I would really like to try and get BTM done first when we arrive on the sunday, presuming it gets dark by 8ish as I would like to do that ride in the dark.
