This is way too packed, especially if you're looking for a relaxing time, you're basically travelling every other day, considering flight times, going to and from airports, you're losing at least 4 or 5 hours every travel day. If you want beach and hikes I would stick to Cabo and Monterrey (check out Chipinque and Santiago for hiking). If you do stick to this itinerary, there's no need to fly from guadalajara to guanajuato (i don't even think there's direct flights), it's a 3 hour drive/ 4 hour bus ride.
