Undoubtedly, the best feature for families about Top of the Rock is the timed admissions: no waiting in line with impatient kids.
Families will also be happy to know that kids under six are admitted free, with a paying adult; and strollers are allowed.
Also, head to the Top of the Rock site for a worksheet to print out: one sheet shows major landmarks that kids can find from the observation deck, another compares 1969 to today, etc.
Kids will definitely enjoy the GPS-enabled audio tour which also displays photos and videos. At time of writing, rental for these devices costs $10, and -- as long as you have plenty of time for your visit-- you can probably take turns with the units among family members.
Also at Rockefeller Center are two other prime attractions: NBC Studio Tours (a great idea with teens who watch NBC shows), and Radio City Music Hall.
