Hi there and welcome,
No the price you pay is for what you get, a really nice single-double room, I have had room witha double beds + a single bed in so your not stuck in a horrid room in the back of beyond I can assure you.
The age range is always a popular question from people so here goes, the core age group I would say is 55-70 but there are also younger and older. Ladies far out way the gentelmen...but I can assure you we always well I do include the men into the mix that's if they want to be included we never force anybody to join in who doesnt feel the need. It is your holiday so you must do and allow the people to do what they want, there is no pressure.
I will be on my 8th tour 2012 and have done long and short haul trips so if I can help you with anything please just ask..there is an interveiw on the main page of my thoughts if you would like to play that.
Cindy
