Does anyone know how much it costs to travel to Yangjiang at one's own expense (without a tour group) for about two days?

According to different places to go to Yangjiang, for example, the fare from Shenzhen to Yangjiang is more than 100 yuan, the fare from Yangjiang to Hailing Island is about 10 yuan, the three-star hotel staying in Yangjiang for one night is more than 100 yuan, and the ticket to Dajiaowan Water Park is more than 30 yuan, plus more than 100 yuan. The fare is almost the same as that of 300 yuan, the accommodation is one hundredth and fifth yuan, the ticket is one hundredth and fifth yuan, and the food is one hundredth and fifth yuan. If you join a group, it will be 450, which is much worse.
