UK theme parks - large venues?

[miked1e]

Apologies, but I do not want to be in the COVID related forums, but understand if this thread is to be moved.

With the potential rollout of COVID passports for large venues, do we know if this will include theme parks? Or more mass events ie concerts, football etc

We have booked to go Legoland in October half term. I have my passport, but DW will only have 2nd vaccine the week after the half term (unless we can bring it forward from 8 weeks after first jab)

I can’t find anything about theme parks.

Thanks in advance
