Best to come back later tonight then, so that you can start putting things into place. After dark the festival venue is closed but for some workers here and there, and security. Nothing that you can't avoid, or use the same excuse of being a volunteer worker.
For how you'll actually grab the money? Well you'll sabotage the stage of course, causing a collapse of some manner. Then in the ensuing chaos you'll get up there and snatch the grand prize! How to do this, well you watched the workers and even partially helped out with setting up the stage, so you know how there are a few key locations that are held up or together by single bolts or pins. Removing one or even a few of them wouldn't do much, but enough of them and the whole thing will start to fall apart under its own weight. Though if you remove them all now the stage won't last till tomorrow so it needs to be done during the event and you need to not be noticed or impeded... with an earlier side-trek you've managed to get some lengths of narrow steel cable that you can loop through a large number of the bolts and pins, and then with enough force just pull them out all together. Of course you're not strong enough yourself for that but with a car or a truck it should be fine, and with the food festival going there's no shortage of trucks around.
Then once you've gotten the money, how to get away from anyone who would stop you? Why, lose your pursuers in the crowds of people gathered for the event! Sadly you would have preferred your ideal supervillain outfit for your first high-profile caper, but having to wear normal clothes does come as a blessing. Once you're able to merge with the crowd it's going to be very difficult for anyone to just easily catch you out from it, especially if the people do get into a panic. Admittedly this part of your plan is the most unpredictable and so it makes you the most nervous to rely on, but it seems better than the other options at least.
Lastly then is the matter of escape... now here is the part where your plan starts to break down. Not for a lack of ideas since you have plenty, but rather which one to settle on? Escape after all, in theory is the most important aspect of all when it comes to a crime. You'd rather the crime failed but you escaped, than if the crime succeeded but you failed to escape! Any of your ideas seem valid but when it comes down to it tomorrow...
