We're just about ready to order our park tickets for April next year, whilst the exchange rate is so good.

We are getting

Universal 7 day 2 park pass
Sea world
Disney 6 day Magic your way base and more 14 day exp with free upgrade to 7 days

I just want to double check that our daughter who will be 2 years 8 months when we go, will not need to pay for any of these parks. Will we need to show her passport to prove that she is under three on the gate?

Many thanks
