If u have a pass but it hasn’t been activated yet do I still need to make a reservation????

It would be the sager choice.

I tried and was told we needed a reservation. I don't know how they would enforce it if you just show up though

We have a pass and went right to the park; didn't make any reservation. If you plan on going on a weekend or holiday, you may want to make a reservation.

Yes I will call one of the Legoland representative so you can get a good answer I'm still thinking yes

Yes
