Harry Potter studio tour, with a 1 yo?

[OneLittleBabyTerror]

DH is a big Harry Potter fan. I'm thinking of treating him (and me and 1yo DD) to the studio tour in Levesden. Would you recommend taking a 1yo in a pushchair? She's very good at sitting in her pushchair and stare at things. But like any toddler, she'd need to eat often, get her nappy changed at irregular times etc. I try to look for info on the website, but it's hard to gather whether we are allowed to just walk around ourselves, or if we have to follow a tour guide around. And how long the 'tour' is if it's guided?

The tour is self guided. You start by going into a holding area then into a cinema for a short show then on into the tour. The first room is open plan really so you can walk about at your leisure. There are toilets available and you can get to them at any time. Once you leave this area you can't re enter.
The next bit is outside with the outdoor sets. This is where the cafe is.

The final part is again self guided but more like following a route rather than the open plan of the first bit.

I don't recall seeing any pushchairs when we were there but it would be fairly easy to negotiate the first bit and the outdoor bit.

I took a 3year old and a 9 year old. The 3 year old ran about l

Sorry pressed post!
The 3 year old ran about like a mad thing and did about 20 laps! In total we were there 3 hours.

There are some restaurants about 5-10 min drive away which were handy for tea before we left.

Thank you that sounds promising. The website says there are only limited space for pushchairs. But I doubt they will make a 1yo walk! (She can't walk yet btw).
