Is it better to travel with a group or by yourself from Chongqing to Bali?

You can only travel freely to Bali, but it is not as good as Sanya if you join a group:)

There is no direct flight. If you leave from Chongqing, you will usually transfer to Hong Kong or Singapore. The most economical way is to start from Shanghai, which is the largest port in Bali and has the most flight choices.

There are 1w8RP stored-value mobile phone cards suitable for China tourists, which are sold in supermarkets. It takes less than 20 minutes to call back, so it's enough to contact there. If you look for a tour guide, you can't find it yourself. It's best to ask the travel agency that booked your air ticket, and make it clear that you don't need to pay for shopping at your own expense, and so on. Just tip enough.

May and June are the best tourist seasons in Bali, with high cost performance:)

The cost of honeymoon guests is generally 8k- 1.2w/ person, and it is more than 6k/person if the accommodation requirements are not high.
