I think it funny that there’s an assumption in this thread that these posters are aimed at U.S. tourists when visitors from the U.K. outnumber the Americans by a factor of six to one.
People in this threat also don't seem to realize how the island of Mallorca is full of foreigners, even some just living there, but nobody speaking Spanish. In fact it's probably easier to get around with German or English in the touristic parts of Mallorca.
This is not about some poor US tourist who wasn't good enough in school back home to learn Spanish. It's about huge crowds of rowdy UK and German tourists who go to "Malle" every year for partying and getting piss drunk without any consideration of the locals.
To be fair, they spent years encouraging that kind of tourism and are no annoyed that they've got to popular. As the article points out it represents 75% of their economic activity so they'd be buggered if everyone just said, fine we'll go somewhere else then.
Nah, not really. They want to change from party tourism, which is concentrated on one small area to a more distributed culture tourism. Those tourist spend twice as much and not only in the big clubs but on small shops all around the island. So they have a plan and it makes sense.
Visas, residency/rental restrictions, curfews, noise ordinances, non local surcharges, resident member beaches (membership fulfilled by residency), or a hundred other things
Edit: example: in palm springs, you cannot have any outdoor music or elevated noise as a non resident.
If you do, you can be evicted from your rental same day
One time I went to a bar in Mallorca, asked "dos cervezas, por favor" and the guy went: "Was? Zwei bier??"
It was surreal to realise that nobody there actually spoke any Spanish. Outside of the tourist traps Mallorca still has some authenticity here and there but it's like the locals just hide in the shadows for the most part.
I'm surprised there's that many Americans tbh, I wouldn't have thought it would be on their radar, I think of Mallorca as a package holiday destination for Western Europeans.
