We are only 10min walk from it which is lined with hotels, restaurants, shops, and dance clubs. And YES it is safe to leave the resort and walk the strip.
If you’re looking for a little more fun outside of the resort Xcaret excursion is one of the best. It’s located in the middle of the jungle surrounded by underground rivers and cenotes. They offer water park, amusement park, and tours. Do your research and when you get to the hotel there will be someone in the lobby to help you book.
