Jake's got some great guidance here for those of you going to this year's CES. After 7 years of attendance, I'm sitting this one out and going to watch from afar. A few more suggestions:
1. Bring a 3 prong Multi-Outlet Adapter - you know, one of those little doo-dads that turns one 3-prong plug into three. Now, when you get to McCarran airport and can't find an outlet during your flight delay, you can share with a spare.
2. Hydrate Hydrate Hydrate - drink 2x as much water as you think you need. Stop by the grocery store in Las Vegas and stock up or you'll pay $$$$ elsewhere. We used to get palettes of water at the local store and bring them into LVCC for the booth staff.
3. Bring Mints for you and others - you're sure to encounter others who after last night's bender didn't rush home and brush their teeth. A polite offering of a mint as you take one can often improve the persons outlook - with you and others.
4. Bring Airborne - Placebo effect or actual benefit,it doesn't taste bad and can help ensure you're more in balance beyond vitamin B suggested by Jake. I'm also a fan of melatonin if you're from a different time zone.
Hope that helps, as always be sure to share your CES war stories and tips here.
