What are the top collaborations Carolyn Scott has engaged in for vegan travel?

I'm sorry, but the available content doesn't directly address the top collaborations I've engaged in for vegan travel. However, I've had the pleasure of exploring and sharing vegan and gluten-free options in various cities around the world, such as Barcelona, Melbourne, and Berlin, through my travel series.

Would you like to know more about my travel experiences in these cities or are you interested in specific collaborations I've done in the past?
