@Shana thought the same so we have booked the day off. So we can either go Monday or Tuesday. We don't mind going to London if we can make a full day out of it, and what I can see bubble planet is a bit out of London. We willing to travel about 1hr or 2hr drive. We based in cambridge.
We're going to the london aquarium on the weekend and on his actual birthday on the Thursday we're taking him to winter wonderland (early) x
I can also recommend the aquarium!
We are off to monkey world for our daughters birthday
It gets really busy so I wouldn’t recommend it for the whole day either personally. I’ve been before and it is good, just gets super packed! How far are you willing to travel??
