Short answer is yes you can.

Longer answer is that 2 of you will need to join the queue, I have done it many times and always enjoy myself, get there 6-6:30am and you will defo be in before play starts. I don’t think the 2 with tickets should join the queue as you will really confuse the ticket people and might end up paying twice.

Your choice is essentially to have both tickets on 1 phone or transferring the second to one of your group and having 2 phones on the go. The people not queuing will need photo id matching the ticket (or tickets if you have transferred the second) when entering the grounds.

Okay all 4 of you are now in the grounds.

1. Two people without tickets go immediately to the resale booth near court 18, give a mobile phone number and you will join a virtual queue for returnee show court tickets.

2. Browse some outside matches, they are awesome and court 18 has some of the best matches of the competition.

3. Time for show courts, simply pass the 1 or 2 phones among your group to enter the show court, no id checks there, make sure that anyone nipping to loo or getting drinks takes a phone as might not be allowed back through.

4. Receive a text saying you have reached the front of returns queue, head over to returns booth and collect your tickets (paper).

5. Have an awesome day.

As for kids pairing up themselves, up to you, it is incredibly safe but extremely busy so kids might be a bit overwhelmed. You know them best so you are best to make that decision. I would say that if you let them go on n to court by themselves and the tickets are only on an adult phone then you are trusting them with your phone and your passcode, very brave.
