Remember to keep an eye on each other in unfamiliar places. One of you may be surrounded by children looking to pickpocket - be sure the other one is watching to avoid unfortunate situations. Perhaps you know enough French to understand that your mate is about to order snails off the menu - help him or her figure it out! And finally, don't overextend yourself. If you know you're particularly susceptible to jet lag, then plan an easy day for when you arrive at your destination. Likewise, your partner may have his or her heart set on visiting a nightclub the night before your flight home. Push back the time if you can in order to allow for extra rest in the morning. Like most of the aspects of your relationship, traveling requires a little extra patience for everyone to have a lot of fun.
