I've been on CTC tours to:
Cuba, Nova Scotia, Romania, Norway, Slovakia, Poland, Hungary, Czech Rep, Slovenia, a folding bike tour of Wales (making use of lots of narrow gauge railways, a mountain bike tour in Iceland and was deputy Leader on a S African tour, all thank to the CTC.
If you choose to go on a tour you'll meet a varied mix of folk, and the type of person you'll meet will be influenced by the type of tour. Certainly on the S African and Scotia tours we had two dancers from the London show cats on board, one male one female, neither had beards, except when in costume I suppose. On the SA tour we had pre-booked places on the Cape Argus, and during the Argus we got plenty of jest from toned would-be racers on high end kit, who who laughed smiled at our mudguard and rack fitted tourers until we overhauled many of them, our camper long flaps flapping in their faces as they crawled on the climbs on their overgeared overpriced kit.
If you are considering going, ring the tour leader, and quiz them on the type of folk they expect, the more arduous tours will have very different folk to the 'week in Norfolk' types. Tour leaders do vary too. As for the comments re shorts we had folk on our tours who had been cycling for years without padding in their shorts, (it is a relatively new invention for many folk) and did not seem to suffer as a result, I prefer to have it myself.
I now lead my own tours for fun, and you will almost certainly come across real ale on my tours, but we tend to drink it, and not talk about it too much.
As I said earlier, quiz the leader, you won't know if you don't try.
Good luck.
