What should foreigners know about hotels and registration in Sanya?
Sanya is a resort town that runs on foreign tourists; the beach-zone hotels in Yalong Bay, Haitang Bay and Dadonghai register foreign guests without blinking. The only places that sometimes can't are cheap inland guesthouses, so confirm when you book the budget end.
What's the main thing to know before visiting Sanya?
The seafood-market weigh game. The classic Sanya move at the seafood squares: a price tag reads '580' and you assume it's the dish, but it means ¥580 per jin (half kilo), and a single fish can be two or three jin. Then there's a 'processing fee' to cook what you bought. Agree the price per jin, watch the scale, and get the rough total before anything goes in the tank-net or the pan. The stalls shouting 'premium seafood' are usually just normal seafood at a markup.
Any tourist traps or surprises to watch for in Sanya?
You're paying for the bay, so pick the right one. Sanya is really three coasts. Dadonghai is cheap, central and crowded - fine if you want to walk to dinner. Yalong Bay has the best sand and the resort wall of five-stars. Haitang Bay is newest and quietest (and where the Wuzhizhou ferry leaves). The water is good everywhere; the difference you pay for is the crowd and the hotel, not the sea.
What should I eat in Sanya?
Buy seafood by the jin, with eyes open. The fun way to eat here is buy-and-cook: pick live seafood at a market stall, pay a restaurant to cook it. The trap is the weighing. Insist on the per-jin price up front, watch them weigh, and confirm the cooking ('processing') fee per dish before you commit. Done right it's great value; done blind it's the most common Sanya rip-off.
Where do locals eat in Sanya, and what else is worth trying?
Wenchang chicken and the Hainan four. Hainan's signature is poached Wenchang chicken - plain-looking, dipped in ginger-and-kumquat sauce, the point is the bird not the heat. It's one of the island's 'four famous dishes' along with Dongshan lamb, Jiaji duck and Hele crab. A local restaurant doing the chicken right beats any seafood tower for a real taste of the place.
How do I not get ripped off at the seafood markets?
Treat every number as price-per-jin (500g) until proven otherwise, and a fish is often several jin. Watch the scale yourself, agree the per-jin rate and the per-dish cooking fee before you hand anything over, and skip stalls that won't quote a total. The buy-and-cook system is genuinely good value when you pin the price first; the overcharging only works on people who don't ask.
Which beach should I base myself near?
Dadonghai if you want cheap and walkable with restaurants at your door; Yalong Bay if you want the best sand and a resort; Haitang Bay if you want quiet and you're island-hopping to Wuzhizhou. The sea is good at all three - you're choosing crowd level and price, not water quality.
Can I use a foreign card in Sanya?
Yes. Foreign Visa/Mastercard link to Alipay and WeChat Pay and cover almost everything - resorts, ferry tickets, restaurants, taxis. Set up the apps before you fly in. Carry a little cash for market stalls and small operators who'd rather not deal with QR refunds on a haggled price.
Do I need to reserve attractions in advance?
Most days you can walk up to Nanshan and Tianya Haijiao, but they run real-name timed entry, so on Chinese public holidays book a slot a day ahead. Wuzhizhou's ferry has daily caps and does sell out in peak season - book that one earlier. Your hotel can handle the Chinese-language bookings with your passport.
