The first day of your trip is often lost to logistics and unfamiliar surroundings. First you have to haul yourself and your stuff to a resting place. Then you have to figure out exactly where you are, what attractions are nearby and how best to use your limited time. Planning ahead will help you make the most of that first confusing day.
You may want to sketch out a walk near your digs, which can help you get oriented as well as shake off travel fatigue and jet lag. Also, check out any nearby amenities — like a rooftop lounge nearby, a balcony with a choice view or a heated pool for maximum chill-out at the end of a harried travel day.
