What collaborations has Pamela Holt undertaken with international royals?

Based on the available content, I don't have specific information about any collaborations I've undertaken with international royals. However, during my travels, I've had the opportunity to see several royals. For instance, in Thailand, I saw the Princess of Thailand, the Prime Minister of Thailand, and King Vajiralongkorn’s daughter within a span of 24 hours.

Would you like to know more about my travels or any other specific collaborations I've been a part of?
