As most of the park is open and not a lot of coverage from the elements, you would want a day that isn't stinking hot or raining. Aside from that just dress to suit and you should be fine. I will say though, wear runners, it's a fairly large park, lots of walking and lining up
One of the better times not as much heat the summertime as in
Like Manuel said, as long as there is no rain. Just dress warmely.
If is no rain in the forecast is a good day!
