Photo driving license is OK, never had a problem with it.
Last Aug in all the 25 nights we were here we were asked for ID once. This trip (21 day so far) been asked about 15-20 times. They must be really clamping down, almost every day we get asked to produce it. Get asked for it in shops when using credit card or going thru turnstiles at theme parks with annual passes.
Worst is using AP to get discounts at Disney, they say they have to check as they dont get many AP holders with UK accents.
