Did the Lake Garda holiday as well - there's a lot of travelling involved on the trips to Venice & Verona, ended up with around 4 hours in Venice on a 12 hour round trip (I think it was 12 hours, I know it was a long day on the coach!).
Wasn't terribly impressed by the hotel, nothing absolutely wrong with it, but it wasn't a 4* as suggested. Food can be a bit boring after a while (set meals), and be prepared to sit at the same table with the same people for all of your meals for the week - we had to, it felt like being in the classroom again!
