We will get to the cemetery around 2pm and don't want to miss the Changing of the Guard. I know they are every 1/2 hr while we're there. Do they limit the groups per each 1/2 hour? I'd hate to miss it and wonder if we should plan on getting to the cemetery earlier? (Our plan is to leave the cemetery right after rush hour so we don't hit the traffic on I-95 N)
Thanks so much.
