I have a standard setup for 4 day trips. It works for the most part, but could always use tweaking based on the hotels.
My trip this month has me in two different hotels than the three I stayed in last month. One new one offers free breakfast and a microwave while the other two offer nothing in the way of free food or food prep.
As mundane as I think it is, some might wonder what goes in a suitcase to survive 4 days/3 nights on the road.
I'll start with non clothing since it might be more interesting?
Eight packets of instant oatmeal - easy to make using the coffee maker...I bring my own spoons can be breakfast or a snack
One instant Macaroni and Cheese - cooked at the hotel with a microwave
One tuna lunch kit - for a snack/meal in a pinch
Ten packets of fruit snacks - healthier than Skittles
Four fiber bars - filling and healthier than Snickers
That ends the food...now for my tech
One Roku XD Box + HDMI cable - new this trip, I don't watch much "real" TV
One Asus WL-330gE router - can take a wireless signal in and rebroadcast another (needed because the Roku box can't click "OK" I will use my Ipad/Phone initially on the connection)
One iHome iHM60 Rechargeable Mini Speaker - better speaker than the Ipad or my phone
Back up alarm clock
Back up headphones - super cheap kind as I break/mispace them often
Backup charging cables for my Zune HD, IPad and HTC Thunderbolt. Main set kept in my messenger style laptop bag
For tolietries I carry
Shaving gel, aftershave and razor
Toothpaste + toothbrush
Enough contact lenses for a week (I wear dailies)
One back up work shirt
Polo style shirt
Two "out and about" t-shirts
One workout shirt
Walk around shorts
Socks and underwear for 5 nights...just in case
Finally I carry an umbrella...didn't know where to place that.
All of this goes into a standard carry on bag.....and it's not overstuffed. It's all about how you pack.
