The earlier plan was to split this post into four... due to many things on my plate, I wanna post ALL remaining best moments in one post and cover my after-STEEMFEST thoughts prompted by @anomadsoul immediately in the next post.
So without further ado, my remaining 38 best moments are:

#38: Stepping into Siam Society for the first time - a lush green place enlivened by pop-pink coloured wooden handfans throughout...

#37: ... transforms into a lovely environment for conversations and ice-breakers. @cryptospa and @anomadsoul

#36: Connecting under a warm sun with @nainaztengra, @buppke & @misslasvegas.

#35: With @poezio - one of the first people I get to meet at STEEMFEST.

#34: Chatting with @aggroed. While we awe his successes with Splinterlands, the reality to get here was far from easy.

#33: @roelandp wearing that.

#32: My first time meeting the new @steemit team. (From L-R) @justinw, @vandeberg, @elipowell, @andrarchy and @roadscape.

#31: @lukestokes thanking the @steemit team for persevering a hard year, increasing revenues and delivering a more grounded plan moving forward.

#30: @aggroed sharing awesome performance numbers for Splinterlands. In a challenging year for STEEM as a whole, it is nice to know that some projects have met success... and we can learn from them.

#29: For example, Deegram shares their next plans is to stop, reflect and find their product-market-fit. It takes a rare humility to admit and share your challenges publicly. Kudos to @robinron, please let us know how we can help.

#28: @dmitrydao giving an update on Steem Proposal System (SPS) and sharing some housekeeping tips for proposal submission.

#27: Probably the highlight of Day One - @vandeberg and @gerbino giving a demonstration of how a smart media token (SMT) can be launched; with or without fundraising option.

#26: Visiting Wat Pathum Wanaram together after Day One Conference.

#25: It is amazing how beautifully serene and tranquil this place is; when just outside its walls is the hustle bustle of a chaotic city. (You can see the Siam Paragon - one of the largest shopping malls here in the background)

#24: Speaking of Siam Paragon... we had our dinner at the bowling alley with (from L-R) @goblinknackers, @slobberchops, and @dylanhobalart.

#23: Practice rounds.

#22: Competitive spirits @jeffjagoe and @bitrocket2020

#21: Entering the post office for Day Two Conference. Yes. It's a post office.

#20: A really nice one.

#19: The energy of the people you meet here is really great :D (From L-R) @starkerz, @misslasvegas, @howo, @anyx, @lukestokes

#18: Meeting @lukestokes and later his wife and army of children.

#17: @gandalf and @elipowell - This is a nice one.

#16: @howo highlighting some serious problems facing STEEM. They are not easy to solve.

#15: @aggroed reminding us why it all matters again - it's about creating trust in a digital world.

#14: @steemrollin demonstrating why decentralised finance (deFi) is the most exciting topic moving into 2020.

#13: So interesting that I decided to participate in @steemrollin's roundtable session immediately after with @buppke.

#12 Always a great sight to see Steemians from all over the world in one spot.

#11 Dinner by the Chao Praya River.

#10 Trying Grab Bike. (Not for everyone - you need to hang on for dear life)

#9 Dutch Pancakes!!! @roelandp
"You got to beat it to eat it." - @khimgoh

#8 Night Market & Thai Sweets

#7 Adventurous - @gamer00 and Leo (son) trying new flavors.

#6 Thai Fish Cakes in all sizes

#5 Deepfried Century Eggs. Yum!!!

#4 Sweet Juicy Pineapples w Pink Salt & Chilli Flakes

#3 Mango Sticky Rice Bingsu by After You. YASSSSS!!!

#2 Pad Thai Noodles I had on Sathorn Road.

#1 The Tom Yum Goong I had on the very first night!
