I try to figure out on my own but i can't get it right on which ailine/route to take. Currently, we are coming from US to HKK to BKK. Arrived in BKK on May 11 at 10:15 am & leave from BKK on May 26 at 4:20 pm. Below is my question. Arrving/departing city can be changed. Should we visit 3 instead of 4 places?

Where should we fly into BKK or SIN first?
Arrived to BKK May 11- stay in BKK - 1 night
Airline from BKK to Siem Reap- Bangkok Air (Round Trip)- 3nights
After Siem Reap -Stay in BKK for 4 nights
Which airline from BKK to SIN?- 3 nights
Which airline from SIN to Phuket - Tigher Air (Round Trip)- 4 nights
Fly back from SIN to US
I need a best route option/Airline for these trips so I won't back track. Thank you

Here's one option:
Fly into Bangkok and stay for 4 nights.
Fly Bangkok to Siem Reap, Bangkok Air, stay for 4 nights
Fly Siem Reap through Bangkok to Phuket on Bangkok Air, stay 4 nights,
Fly Phuket to Singapore (several airlines do this route non-stop) stay in Singapore 3 or 4 nights.

Thank you Kathie. I read all of your reviwes and is hard to decide which hotel to stay. Which one is your favorite service apartment and hotel in BKK, Siem Reap, SIN and Phuket?

There are many, mnay wonderful places to stay in all of those locations.

My fave in Bangkok is the Sheraton Royal Orchid in the Towers.

In Siem Reap, I might choose La Residence or the Victoria or Hotel de la Paix

In SIngapore, I like the Fairmont.

But as I said, there ar many options or you.

Kathie: How do you get to malls such as MBK, Emporium, Chitom once you get on the hotel river boat? How do you get back from the Bangkok city to catch the hotel boat to take us back to the hotel? Thank you. Never stay at the riverside.

You take the hotel shuttle boat to the pier below the Skytrain, walk up the stairs to the station, buy your ticket and get on the train. Likewise, when you return, you take the Skytrain to Saphan Taksim, walk down to the pier and get on the hotel shuttle boat. Notice which pier your hotel shuttle leaves from, as there are a series of docks there. The Sheraton boat leaves from the dock on the farthest left as you face the river.

Thank you again Kathie. No clue on which hotels to stay but reading all your reviews, it hleps. You always give precise answer. I sent an email to Bob too. He likes Marriott and JW Marriott in Khao Lak.

Personally might pare back for better experience.Skip Singapor ebig expensive kind out out of the way fly Thai or airasia.com booking.com for excellent hotels. More time at theangkorguide.net largest temple complex in Asia. booking.com
zolitude.com pretty neat for me best in Phuket.

Happy Planning!

Marriotts JW a good bet everywhere.Just snagged there new no foreign fee Visa CC with Chase got 70000 Marriott points good for free JW stays club floor suite upgrades.Might have a lok and a book at Marriott.com super everywhere for me.Any offer is good for 90 days they have reduced the offer to 50000 but
if you ask they will still honor the 70000 for up to 90 days
