They'd probably let you in. We had the grandkids with a sled, there's a small hill they had a blast on, and didn't have to stand in line like you do inside.
They were flexible with us
I had a 7 pm ticket. Walked right in at 6:20
You can get there earlier, but won't be able to get in until 6:00.
You can always try. But I think that they want people to as close to their time as possible.
