Do yourself a favour and bring some cough sweet and - most important - enough water with you when doing demos of your game. You will talk the whole time at the booth, you will meet some interesting people all 30 minutes and you will want to bring all your enthusiasm for your game to those without noticing how exhausting this is for your whole body.. there will be also gazillion interesting things that happen around you, quite overwhelming when being there the first time.I did some days demoing once in a booth with 12+/- gaming tables and these were the lessons I learned.
