OOOORRRRR.... people with trips of more than 8-12 hours should plan their trips they feel is best for them and their family.. For me, leaving the house at 2AM and driving the 16-18 hours to WDW is a piece of cake, don't need anyone telling me what I should and shouldn't do considering they don't know me.. Just because you don't feel comfortable making the trip, doesn't mean I don't..
I have been driving overnight trips for many, many years and very rarely do I see accidents during the midnight-5AM time, most of the accidents are during the day when traffic is heavier..
Maybe I should limit my advice to those posters who are asking what energy drink or food will allow them to safely drive all night. People who aren't sure if they can drive all night or are looking for a magic way to drive all night shouldn't be driving all night.
There are some people who work the night shift. No problem driving all night. There are some people who can adapt to a different sleep cycle. No problem. Sounds like you're in that category.
JMO but a poster who's looking for a way to stay awake or who "thinks" he can stay "awake enough" is a poster who should be looking for a place to stay.
