We had reservations there a few years ago. They do let you in early. I am a bit confused with your post though..... Did you actually mean that the park would NOT be open at the time of your reservation? When we had ours... the park was NOT actually open yet. I can't remember how exactly they handled this.... but as you can imagine, everyone else that also has the first reservations of the day would be dealing with the same issue. Sorry I couldn't be of more help with more details..... But, yes, they do let you in early for you reservation. (I think you only have to be there about 15-20 before the actual reservation.)
