I'm traveling to various cities in Europe like Lucerne, Rome, Vienna- which have tourist passes/ travel passes with unlimited access to all transportation, and sometimes sightseeing discounts and entries.
I'm not able to figure out if it's cheaper for 4 adults to just buy their own tickets, and travel by taxi, than to buy these passes.
I'm also totally confused about the many passes Rome offers. I'm going in peak season- so definitely want skip the line tickets to main attractions like colosseum, vatican etc- which pass would be best for me and my group, or are individual tickets ideal?
Also are there many senior discounts in Europe for non-EU citizens?
