DH & I are planning a long-weekend away WITHOUT CHILDREN [shock][grin][wine] in early October & like to sound of Lucca. We've read that Florence is an easy train ride for a day out & Lucca town itself is lovely to stroll around but not sure if it's worthy of a 3 night stay. Has anyone been & if you'd recommend it can you suggest a decent (probably 3+/4*) hotel? Other places on the shortlist are Dubrovnik & Istanbul.
