Just wanted to know if there is a gym of any kind on the hotel grounds? Thanks.
Not likely. It's not a "gym" sort of place. Besides, the new definition of "all inclusive" translates to "some things included", which especially applies to "budget" all-inclusive. Beer is included though.
There are several gyms in Manacor, a 20 min. bus ride. There's one within a short walk of the bus stop in the center, and another not far from the bus stop at the train station, just across from the Mallorca pearls shop. It's called (ironically) "GB", although you won't hear a word of English...
