In Illinois, the wait seems to average about three hours. Unfortunately in our family of five, we all have expiring licenses, so we've decided to bite the bullet and put up with the lines. We all have GE cards, but will get the Real ID as well so we don't have to carry both cards to travel. Son's wait during a college/holiday break was 3.5 hours arriving at DMV opening, husband's was 2.75 hours with mid-afternoon arrival, my poor 85 yo mother waited 4 hours and then had to return because the "system" was down (and couldn't take the photo), our daughters and I have yet to go but will get the Real ID since we have to renew anyway.
Those waits are horrendous. I am not sure I could wait that long.
I had to delay getting my star because I couldn't find my SS card. I had almost given up (thinking I will just need to travel with my passport) when my wife found it tucked away in a folder with our marriage certificate. I went to the local AAA office and was in and out in 30 minutes. Thankfully this was 18 months after MA had implemented the new ID's so almost everyone who wanted one had already obtained their new license.
