There you go buddy!!!!
I assure you that Pierre is not in Catalonia, Spain. That is a chain of Hotels all over the world. If you notice, if that photo, there are to more boards saying "la banda", a very well known group of Mexican musicians.
Catalonia hotels are most of them in the Caribbean, well in Dominican Republic, Jamaica, Cuba and Mexico. That photo with palm trees moving with strong wind is also a clue, and that kind of sand beach is rarely found in anywhere Spain but Ibiza perhaps, never in Catalonia.
And finally, the photos where Pierre appears submerge in turquese waters are not caves. These are the famous "cenotes", natural holes below earth surfaces made by subterranean waters where the Mayas threw up virgin girls sacrificing them to Chac, their Rain God, so that he would be magnanimous and send them rains that provide good harvests. Today, those cenotes are used by tourist tours as natural pools to dive and enjoyment.
So as you have said above, I think Pierre is somewhere in Mexico, probably the Riviera Maya, at some point between Cancun and Tulum, near Puerto del Carmen.
And if I'm wrong, let Pierre correct me, but if Pierre is in Spain, with those waters and white sand, it can just be in Menorca or Ibiza, but never Catalonia. And I keep my guess to Riviera Maya, Mexico
