Not sure, possibly due to covid regulations only so many reservations?
Agree with the previous 2 about being sold out for reaching maximum capacity...although I disagree with the 3rd party vendor option because on their website they say tickets bought thru other parties / vendors will not be acknowledged and can possible be fake so I would be careful...if you are able to acquire tickets I would call Lego land and ask before purchasing
Second the previous answer. They only allow a limited amount of people in per day. Looks like your day is sold out. Try a 3rd party vendor.
