Im from Ireland and I have been to Florida, California and Paris.
Florida will always be in my heart as it was my first experience of a Disney Park. I went there with my family in the 1990's, before the magic bands / fp+ It was where I fell in love with the Disney Park experience but Im not sure I want to go back there now, as so much has changed.
California is my "home park" I just love everything about it. Its the first Disney park I discovered and explored as an adult. Its the park that Walt put his heart into. For me its more doable than Florida, as I dont drive and and have a limited budget. The fact that the 2 parks are walkable, paper fast passes and its close to LA where my friends live.
Paris is my mini break escape park. Its more "local" to me than the USA parks. I go here less frequent than California, To me it does not feel like a real Disney park. Maybe because I go in off season when its cheaper and the weather is not the best, no blazing Cali sunshine. Even though I stay onsite in France, I feel more in the Disney bubble in California, where I stay off site. France gets me by when I nee an extra dose of Disney.
