If you're a frequent traveler and need to know how to get back to the right hotel room at night, this is a very simple, but also very handy tip. Lets set the scene: you check into another hotel on your travels and you're given a plastic key card as well a small piece of card with your room details printed on it.

The first thing you do when you go out later, is pick up the plastic keycard but leave the card with all the details on in your room. When you return later in the evening, exhausted from the business meeting or intoxicated from the on expenses alcohol splurge, you have forgotten your hotel room number. As it is never printed on the programmable plastic keycards, you're in a bit of trouble.

Read on after the break for our great solution to this dilemma!

The simple solution is to take a picture of your room number with your iPhone before you go out. When you return later, simply fire up the Photos app and there you have your room details and you're all set to get that good nights sleep. No more embarrassing visits to the hotel reception to contend with. Hey, I said it was simple, but it is also a great tip!
