Field notes
Day 1: land, walk, eat
Base in Old San Juan, Condado, or Isla Verde. Walk the historic core, choose one food stop, and keep the first night simple.
Day 2: one big memory
Pick El Yunque, bio bay, catamaran, or a food tour. Do not stack three high-effort activities in one day.
Day 3: brunch and beach buffer
Leave room for late checkout, beach time, souvenirs, and airport reality.
