Ran across a few of these and thought I'd share. Most of you probably already know these. But, I'm a caveman technology-wise and I just found 'em.

Carry some cash and your ID between the phone and phone case. Eliminates the need to carry your wallet.

If your hotel room doesn't have enough electrical outlets, charge your phone off of one of the plugs on the back of your TV.

Next, if you are going to be out in the elements, put your phone in a Ziploc baggie. It will still work fine.

Also, if you rely on the alarm on your phone, put the phone in a coffee cup. This will amplify the sound and you won't get up late.

Here's one for me. Take pictures of landmarks where you park your car. It will help you find it when your done at your event.

Have everyone in your group download the "Find My Friends" app. That way, if you get separated from your group, you can find each other via your phones.
