Hello, Claire
I haven't been on the Prague, Vienna and Budapest trip but, although there were one or two comments about a not-very-good hotel, I think if you go into the Search section and put the holiday in you will find that there have also since been ones to the effect that the hotel which caused the problems has been changed. If these cities are ones you really want to see, I wouldn't let one less-than-perfect hotel put you off.
As to the Highlights of Tuscany holiday, I did this in 2011 (I think) and thoroughly enjoyed it. Again, if you enter "Tuscany" in the Search section you will find a host of comments on it - and I am sure Cindy will come back to you on this one as she did it the year after me.
