Perhaps unfortunately for them, the squad - who are currently top of the SPL - were not taking a Costa Calida holiday themselves, but were training for the final few games of the season.
However, according to La Manga Club, the Celtic players and staff still had time to take advantage of the golf course and the health spa - just some of the amenities that Costa Calida holidays can offer.
Jan Vennegoor of Hesselink, Celtic's Dutch striker, said the Costa Calida experience had been excellent. He added: "They have great pitches, but you also have the good weather and everything comes together."
Costa Calida, which literally means warm coast in Spanish, has won over many thousands of tourists taking villa holidays over the years - with its balmy climate and stunning scenery.
