I think your chances are good, but there are no guarantees. There are no tables for 1 in BOG, so it's probably more about controlling numbers in the restaurant than seating people at tables. I would go to the kiosk and just ask really nicely if you can bring your child with you, but be prepared for a no. We've walked up to BOG twice for lunch with a party of 2. Once, I noticed a reservation for 1 was available while we were in MK, so instead of making the ADR, we ran over to BOG and asked if they could seat 2 of us and they let us in. The second time, we simply walked up, I asked nicely if there was any chance we could get in. The CM looked at the crowd on the bridge (which wasn't backed up), handed us two menus and told us to enjoy.
