In 2011 I was co-initiator and organizer of GayDay@Efteling. On June 11 of that year, 1,500 people, dressed in red (analogous to Gay Days Disney) came to the Efteling.
Participants came from the Netherlands, Belgium and Germany. Transport per bus was arranged for, hostesses present. A large raffle with over 100 prizes was organized to fire up ticket sales, made possible by around 30 sponsors, which I got on board.
Guest received a goodie bag at the end of the day, worth € 100 – thanks to the sponsors.
GayDay@Efteling will probably get a follow-up in 2016 as FunGayDay!
