Barbados is a coral island with two coasts that do not feel like the same holiday: the west (Platinum) is calmer water and hotels; the south is St. Lawrence Gap and Oistins; the east is Atlantic crash and soup bowls at Bathsheba. Bridgetown's Garrison is UNESCO, not a cruise-shop alley you skip for the beach.
ZR vans are the public transport — yellow buses with a stripe, a conductor, and a shouted destination. You pay in Barbadian dollars (BBD); US dollars appear on resort folios at a known peg, but the ZR wants Bajan notes. Eat cou-cou and flying fish, the national plate; Friday night at Oistins is grilled fish and tables in the car park, not a hotel luau.
Grantley Adams (BGI) sits on the south. Flow and Digicel cover the populated south and west more thickly than a hike on the east coast. An eSIM live at the jetway means the ZR destination, the west-coast villa gate, and the Oistins taxi are not a hunt for a kiosk after a delayed Virgin or British Airways arrival.
