Hello Sheila,
I was on the Lake Garda trip in June 2011. A great trip if you are on the opera at Verona. We saw Aida which was amazing. Look for the bus number, loads of coaches that one lady got on with the wrong group- no wonder she did not recognise anyone !
Loved Venice, they arranged for us to go on a gondola and had tea on the Plaza at St Marks. Lunch at the restaurant up in the mountains was lovely, the drive not so much :P
Trip on the Lake was beautiful. Almost like a bus with stops but on a boat instead. Must try gelato -ice cream- as it is gorgeous.
Have a wonderful time.
Jan
