No, if you have a 1-Day ticket you must visit LEGOLAND and the Water Park on the same day. However, if you have a 2-Day ticket that includes the Water Park then you can spend all your time at LEGOLAND on your first day and spend all of your time at the Water Park on the 2nd day. Please keep in mind, the Water Park is inside LEGOLAND therefore you would need to enter LEGOLAND to access the Water Park. Also, the Water Park's hours are shorter. Please check the calendar for our hours here.
