Coming to Zi in 3 weeks. Have seen pedestrian walkway mentioned in different posts. Where is it located and is it like a 'boardwalk' like the ones we have at the Jersey Shore in NJ loaded with stands or just a good place for a stroll? Also saw mention of walking down to different restaurants on the beach. I am staying at the Tides. How far a walk would some of these restaurants be and do I use pesos, dollars or CC? Sorry for these stupid questions but haven't had vacation outside US in 35 years.
