Alright...adding my methods
(this is based on a 1 week stay...I'd reduce clothing etc for shorter stays)
I think I need to look into the packing cubes...but short of that...this is the plan for me.
1 laptop case (generally semi-hard sides) with:
aluminum foil
clear wrap
small baggies
no-stick spray
spices
laundry detergent
room scent (candles and spray)
toiletries (In ziplocks to prevent spillage messes: moisturizer, shampoo, conditioner, razors, aftershave, hairspray, q-tips, cologne/perfume)
Carry-on*:
snacks & toys(if kids are going)
book(s)
bathing suits
toothpaste & toothbrushes
deoderant
glasses/contacts
sunblock
eyeliner (it's my only girly concession that I use daily)
medication (motrin, neosporin, bandaids, and prescriptions)
camera
cell-phones
chargers for whatever we're bringing
travel chess/checkers set
small (24 disc) travel pac with cd's and dvd's
travel itineraries/tickets
purse
Jacket/fleece (even if heading to warm areas...nights can be chilly depending on what you're wearing)
*(if you're wearing decent clothing designed for your destination and your luggage gets lost...you're still good to go with this carry-on)
Luggage:
clothing appropriate for destination...as little as possible to get by (consider that most of us have a washer/dryer or access to one)
mini bag (little 5 inch flat square that unfolds into a duffel bag in case we get stupid and feel the need to buy everything in sight and bring it home with us)
If going to a drive-to resort:
cooler with:
frozen meats & fish
veggies
pre-made pancakes or french toast (easy to nuke...no cleanup)
butter
syrup
eggs
ham (sliced thin for sandwiches/thick for breakfast)
bread
crackers
cheese
grapes and apples
condiments (small mayo, ketchup, mustard, ranch or ceasar)
*if going close by with the kids we'll usually pack more kids toys (playstation and legos) and board games too... for use in the car and while at the resort during down time or rainy days.
