60 days is the time period if you are booking through Disney. You can book private excursions many months in advance. for example, we are cruising in January and we've already booked stingray city in GC and the dolphin swim in Coz.
I am 51 days out and just got my information from DCL regarding excursions in the mail today. But if they say 60 days and you are anxious to get them reserved, I'd look at the availabilities online and call at the 60 days.
I just called a few moments ago and reserved my 1st choice parasailing time.
