We're getting the Birkenhead ferry across to Belfast, and taking the car. We're doing the overnight crossing, which leaves at 10:30 at night. We're travelling across country to get there anyway, so it's going to take us hours just to get to the port. I don't want to worry about getting stuck on the motorways in rush hour traffic, so would prefer to get nearby quite early. However, even assuming that check-in opens a couple of hours before sailing, what is there to do nearby that will keep a toddler and child amused? I can't see soft-play areas being open at 8 o'clock at night. Any tips from seasoned travellers? The only option I could come up with is the cinema, but that won't work with the toddler.
