How soon after prolonged sun exposure is it safe to have a glycolic acid peel?

I have a glycolic acid peel scheduled for today, yesterday we decided to go to the water park, unplanned, and I was in the sun on and off for about 5 hours. It was cloudy at times and I did wear sunscreen only stopping to reapply once. I do not burn, but I did tan. I did have a bit of redness yesterday but no irritation whatsoever. Is it safe to keep my appointment or should I reschedule? If so, for how many days after?
