I have been Thailand in July,2018. They said Thailand is for bachelors and not for couples. But no i think thailand is the best place for your honeymoon and family vacation.
If you want to travel but you'r budget is not much than you can choose thailand for your budget friendly travel destination. A couple can easily visit thailand for a week in 60 to 70k. And more for your concern you don't need Visa for thailand. You can have on arrival visa from airport in Thailand.
There are many Cities in Thailand you can visit. Bangkok, pataya, phuket, krabi etc.. and so many islands out there for relaxing and peacefull atmosphere for nature lover people.
We visited krabi ,phuket and yao yai islands in our trip. All we get was peaceful environment and blue natural water.
