I have a 2 day pass to Legoland do I have to use it in consecutive days or just same week or month or year?

I got mine from Groupon and it is consecutive

U can use any time if the flexible tickets

Flexible tickets can be used any time.

You can use it one day before the expiration date or just schedule a date to go but it has to be before the expiration date,

It depends on where you got them ... call information

It depends where you bought them , if you bought at Costco it is 90 days from the day you use them first time.

Look at pass for rules
