Should I stay out of the sun?

I got really bad sunburned last weekend on my shoulder then it went to tan and now the tan is peeling :/ I even put aloe on from the time i got sunburned too. Now, I've been putting on Aveeno moisturizing lotion and Aloe gel like crazy. I put on the Aloe twice last night and twice today. I've put on the Aveeno moisturizer every hour today. I made the mistake yesterday of peeling the tan/sunburn so it's pink right there and every time i put something on it stings. One of the bad things is I was suppose to go to a waterpark on saturday. Can i still go? Will it be gone by then?(it's gotten a lot better) What if i put on spf 100 sunscreen every hour?
