Personally I don't think you will get a great few. I am legally blind with a guide dog, so my family has been very accomodating to me and although we have tried, we never stay in the crowd for the fireworks, just to much for me and dog. So next week I am surprising my family with a fireworks desert party at tomorrow land Terrance. I know some say it is not the absolute best view, but for our family not to be in the crowd is all we want, me and my dog always get stepped on, pushed and nervous, so it is well worth the $100 for the five of us, to be able to sit in a much less crowded balcony where the family will enjoy the first fireworks show in 25 years of going, except from the balcony of a hotel across the street from dlr or on the beach at poly.
That may be a better setting for you also.
. Yes we got there early to be able to request a table by the window. They told us the earliest they can check you in is 10-15 mins. I think it's easier for larger groups to get window seats... How many are in your group? There seemed to be more 4 tops than 2 tops by the window. I remember only seeing 2 tables for 2.
Many of the fireworks are set off from near or beside the castle, and so for safety they can not let people near it. They rope it off before the show starts, and then do not let the ropes down until about 10 minutes afterwards so they can be sure "there is no gunpowder left on the ground" (According to the CM who was getting very irritated at our constant begging to be let through!)
