Just a heads up for those of you with tickets to the Sky Garden in London. If it happens that you're running late, don't assume that all is lost. We went about a week and a half ago and showed up a full hour late for our 4:15PM slot. When we showed the guy our tickets, he didn't look twice and scanned us right in. Let me be clear - I am NOT advocating for people to deliberately show up late. All I am saying is that if unforeseen circumstances cause you to be late, don't assume that they will or won't let you in. Just show up with your ticket and keep your fingers crossed.

Plus, you could arrive on time, then stand in that horrendous line for an hour. Been there, done that.
