Absolutely - we always get there before they open. They're pretty good about opening doors relatively on time.Probably going this year. Usually go every 2-3 years. My advice is go early as possible. Get there before the crowds, get there when they open so you have time. It takes couple hours to walk it.
I wouldn't recommend going any time after that anyway. Get there before it opens, and be out by lunch, before the giant crowds hit.If a date is selected I may be able to attend, morning would be best for me as well.
