I'll be traveling through Italy with my girlfriend in a couple of weeks and plan to propose during the trip. I'll be in Florence for 1 night and 1 morning and I would love to propose at the top of the dome cuppola. Is this something that's feasible and what would be the best time to go, ie; less crowds, sunset, etc? Can I send an email or call ahead of time to set anything up and/or ensure I can get to the top of the dome without too much of a wait?
