It's not a long walk. From the Rio Park, turn left as you leave the main entrance and walk down the lane to the first junction, which is Calle Jaen. Turn left on to Calle Jaen and then first right on to Calle Cuenca. Walk downhill on Calle Cuenca and turn third left on to Calle Gerona. Walking along Calle Gerona, you will find the Ambassador Playa on the left hand side.
Sticking to well-lit streets at night you should be fine, there is no need to walk the length of the Yellow Brick Road for that journey.
If you check out our
Benidorm Levante map, Hotel Rio Park is indicated by the number 99 on grid reference L10, and the Hotel Ambassador Playa is indicated by the number 15 on grid reference L11
