I made ADRs on my laptop this morning. It just asked for how many guests and then linked it to my profile guests which I called in and booked. Well looking online I noticed they had my husband and 11 year old listed as infants. I saw they have a modify button to fix but I decided not to try it since one of the reservations was for BOG and I didn't want to lose it. After talking to the operator she informed me I did the right thing because to modify online is a two step process. They cancel your reservation and rebook it so the reservation may not have been available when it tried rebook. The operator made the adjustment without canceling my reservations. Just thought I would pass this along.
