8. Don’t wear uncomfortable shoes
This probably comes as an obvious suggestion, but it’s crucial, crucial, crucial to wear as many comfortable shoes as you can on your trip. Leave the flip flops at home or at your hotel.

The last thing you want to do is go back to your hotel room in the middle of your day just to change your shoes.
