Excuse me, is there a ship from Gao Long Sai Ling Island to Gao Long Island? How much is the fare? How many flights are there every day ?

I have been to all of them. The ticket price depends on which ship you take. It's usually around 10-20 US dollars. You need to ask at a small hotel about the schedule. If you want to stay on the island, it's better to find a hotel run by locals. It's more cost-effective, and foreigners' hotels are much more expensive.
