my advice:
1)BRING YOUR OWN FOOD
stuff like breads, its not a garuntee that your going to have a fridge or a microwave, some hotels do. ramen is good, all hotels have a coffee pot I think to heat up water.
[removed text encouraging room stuffing -JeffT, Administrator]3)energy wise:
GET UP EARLY THE FIST DAY even if your already registered, its fun just to walk around and have fun to : ) you dont have to be in the line, last year i remeber just walking circles around the line early in the morning and I met some great people that way!
also, try 5 hour energy instead of energy drinks ONLY IF YOU REALLY NEED TO its better for you and it doesnt ahve as big of a crash. it tastes nasty but i use it for all nighters.
and here are some tips for keeping awake:
when and doubt stand on your head. it wakes you up believe it or not. it gets your blood moving
4) KEEP YOUR CELL PHONE ON
bring a charger
and if your in a group MAKE SURE that you have EVERYONES NUMBER
5) make friends <3 this is a GREAT place for friends, cause hey we all share the same fandom after all right?
i made a lot of really great friends this way : ) just go up and talk to people, dont be all "OMG BEST BUDS" five minutes after meeting them, but just enjoy your time
6) BREAKFAST
it gets you going, with out breakfast your body fails pretty much
eat good things, not just a box of poky, for instance im baking some muffins that I'm gonna take with our group for the first day so we have something to eat in the morning
7) establish some rules for you rhotel room
they dont have to be incredibley strict but they keep things running smoothly
if your sharring a room, take a shower while the others are asleep, you get the hot water, and then your not holding it up for every one
9) explore the city, go outside of the con area a bit : ) theres almost always a park next door, and this year we have a mall and pioneer square really close by (cosplayers invade down town much?)
thats my advice : ) i hope it comes in handy
