Know if you’re waiting to buy a ticket or if you’re waiting to get in. A lot of sites have one line to buy a ticket and a separate line to get into the attraction. If you’re in the wrong line, you’ve just wasted a lot of time for nothing. When in doubt, just go to the front and ask. Don’t cut in line but at least ask or observe what’s going on to make sure you’re in the right que.
If you need to buy a ticket, try to find a ticket kiosk instead of waiting in line to buy a ticket at the booth. There’s usually a row of unused kiosks in all different languages for you to buy your ticket with no line. This doesn’t just apply for tourist sites but to any automated process. Unless you enjoy waiting in long lines, find the kiosk and learn how to use it even if it isn’t in your language. Remember that the design of the kiosk is meant to be intuitive and easy to use for any citizen of that country which means illiteracy was probably thought about in the design.
After you buy your ticket, get in line to get into the attraction. But even then, use some common sense and be creative. Again, at no point am I saying be rude to others and cheat your way to the front of the line. But, if there is a main line of random tourists waiting and a separate entrance for large tour groups (as is typically the case) and you happen to walk in with that group, I see nothing wrong with that. You’ve paid your ticket so you can always plead ignorance on where to go.
These are just some of the advantages of being the single traveler. I get to blend in and in many cases, being mobile and flexible are huge benefits to getting in and around tourist sites that would otherwise slow me down.
