Hello!

Seeking the collective knowledge of the board after hours of reading through existing threads. I'll preface this by saying any planning I'm doing will be contingent on it being safe/allowed to travel due to COVID-19.

Partner and I have booked flights from Seattle to Singapore from Aug 1 to Aug 16. Having been to SIN before, we'll likely only spend ~4 days there which opens us up to venturing somewhere else for the remainder of our time (~10 days). Seeking your recommendations on where that somewhere else should be.

We're both early 30s and are seeking a destination on the more "relaxing" side of things. For accommodations we're in between the "budget hotel" and "5-star resort" opposites but tend to air on the nicer side if the value seems there.

Requirements
- Within a couple hour flight from SIN
- No big cities
- On the beach (we don't snorkel or scuba, just really enjoy relaxing beach time)
- We love walking so a walkable town is a plus (shopping is not a priority)
- Restaurants/bar variety but no need for nightclubs
- Not overly touristy but we understand some level of tourism is expected and appreciated as we won't speak the language

Initial Thoughts
Off the table are Bali (planned for October) and the Philippines (planned for 2021). Langkawi appears to be a good fit. I've seen mentions of Malaysian Borneo as being more appealing than options on the the peninsula. Phuket seems a bit more "lively" than we are looking for this trip.

Any other places I should focus my research on?

Thanks!
Matt
