Platinum Premier with two rooms booked on reward stay at the Philadelphia Convention Center Marriott.

Its our first time letting our son take a friend. I booked the rooms with one adult, one child each and requested adjoining rooms.

I want/need the rooms to adjoin our room for a number of reasons.

What is the best way to secure adjoining rooms? Call the hotel directly? How far ahead of time?
