Need advice: South East Asia (June - July) best beach /snorkelling destination

Hi everyone,

I’ll be flying to Kuala Lumpur in June and will stay there around 20 days.

Besides spending a few days there, I want mainly to go in a sunny, no rain, and nice beach destination with nice snorkelling.

Please don’t suggest Semporna, the prices are CRAZY !

I was thinking about Flores: Komodo and Riung 17 islands.

I don’t want to go to Sulawesi this year since I’m planning to do it next year.

Do you have any other suggestions ?

Thanks in advance for the kind replies:)
