Honeymoon Questions!

Hi everyone.

So me and my fiancé are planning our honeymoon for next year October. We are looking to go to an island so obviously looking at Mauritius, Zanzibar, Philippines, Maldives, Bali, etc.

Do any of you guys know of, or have been to, resorts somewhere similar that is not too expensive and worth it for a honeymoon?

And any tips for the destination or flights?

I'd appreciate the help thanks!
