Hi, What date in September are you going to Lake Garda?
I went to Lake Garda & the Verona Opera Festival in June, 2013 & had fabulous time.
The hotel & staff are lovely, our tour guide Silvia & coach drive Fabio are wonderful & my travelling companions were great & I'm in regular contact with several of them.
I adore Venice.
You'll have wonderful time & holiday.
Take care,
