I travelled to Lake Garda with the Travel Dept last year, and agree that the hotel wasn't as good as it could have been (we got the "cheap" rooms in the annexe beside the bar instead of the posher hotel rooms!) and early starts and long bus journeys were a feature. The hotel seemed a tad suspicious of us too...until we found that an earlier Irish group tried to leave without settling up bills - perhaps we got lesser service as a result?
The age range was from late 20s/early 30s up to retired folk.
I went to China in 2004 with Travelsphere (a UK company) and found the itineraries, organisation and value for money second to none. The company have been touring in China for years, and are very experienced.
Looking at Egypt myself for 2007 (must be the SSIAs!) and if you want an organised tour, check out CIE Tours international who seem to offer some good packages - unless our readers know different?!
