A little tip regarding "full". You are allowed 10 regions on each server and you will always be allowed onto a full server if you have a region already created on that server. So just create a region on each server and you'll always be able to get on each server you want. I think it is a little more then just creating a region so just create a few roads and lay down some zones or something to create a save of an actual city.

You will likely still have to wait but at least you can eventually get on the server and play with a friend for the first time.Q: What does it mean if a server is listed as FULL or BUSY?
A: If a server is listed as BUSY, this is a notification that there is heavy activity on that particular server. You can still join it if you wish to start a new region or city; or load a pre-existing city. If a server is listed as FULL, you will not be allowed to join that server unless you have an earlier city saved on it. If you already have a city saved on that server, the server will be accessible.
Q: How many servers can I exist on?
A: Players will be able to play on multiple servers, with a maximum of 10 regions on each.
