I know next to nothing about the Thai royals. I heard on BBC world news this morning that the crown prince is very unpopular. It will be interesting to see what happens.
I do know that I'd like to see pressure put on the government to do something about the pedophilia tourism that this country is notorious for. There's zero excuse whatsoever for Thailand to allow this to happen.
Just found an article about him :

"Crown prince is best known for making his poodle Foo Foo an air chief marshal, but his darker side has long caused concerns about his potential rule"
https://www.theguardian.c...ongkorn-crown-prince-kingThe country?s fierce l?se-majest? laws, officially designed to protect much-loved King Bhumibol Adulyadej and his family from defamation, have kept the prince?s stranger exploits out of the Thai media, but the cover-up is only cosmetic.
Stories about Vajiralongkorn are a gossip mainstay nationwide, and he is loathed by many of his future subjects, including the elite circles expected to crown him and then help him rule.
?The l?se-majest? law criminalises publication of the prince?s exploits, but despite this, or indeed because of this, Thais have voracious interest in informal royal information and gossip, which they share privately with those they trust,? said Andrew McGregor Marshall, a British journalist who has written extensively on the monarchy.
?Almost all Thais know about the exploits of the crown prince, who has been a hated figure in Thailand since the 1970s.?
Distaste for the prince was spelt out in a leaked US diplomatic cable from 2010, in which members of the Thai privy council openly discussed their concerns about Vajiralongkorn including his meddling in politics and ?embarrassing financial transactions?.
?Anand [Panyarachun, the former prime minister] added that the consensus view among many Thai was that the Crown Prince could not stop either, nor would he be able, at age 57, to rectify his behaviour,? the cable reads.
In conversations with the then US ambassador summarised in the cable, Thai officials also discussed the hope shared by many in the elite ? but since all-but abandoned ? that the King would appoint his widely respected daughter, Princess Maha Chakri Sirindhorn, as heir. Thailand has never had a ruling queen, and the laws of succession specify a male heir.
?If the Crown Prince were to die, anything could happen, and maybe Prathep [Sirindhorn] could succeed,? the cable quotes the late air chief marshal Siddhi Savetsila saying ?almost hopefully?.
