Avoiding lines — the long and short of it
As far as I’m concerned, there are two IQs for travelers: those who queue and those who don’t. If you plan ahead, you can avoid nearly every line that tourists suffer through (except for security checks).
Many museums are free one day a month — a great deal for locals, but for visitors it’s generally worth paying the entrance fee on a different day to avoid the hordes on a museum’s free day. The Sistine Chapel feels more like the Sardine Chapel when it’s open and free on the last Sunday of the month.
