10hr Layover

Hi all, hoping for some help. I am currently booking a trip to Peru and there is a flight back home that id cheaper. Cheaper because it involves a 10 and half hour layover in punta cana. Looks great because it is during thr day arrive around 9 am and leave that evening around 7pm this is at thr end of November. I was wondering if anyone had any experience with this. If it is worth it to leave not to the beach but maybe the mall I saw was nearby? Or something else that might be close and worth seeing?
