Hi Sharonz, im sure yo will find plenty to do for your 11 year old son,
Were your hotel is situated next to the beach and the harbour , you will find there is a park called goody goody park loads for kids to do also further on round the harbour you have another amusment place but im not sure what the name of that one is.
If you like water parks there is one 20 mins walk away from were your hotel is, also i do advise taking a trip to Cuitedella town as i thought it was lovely and very spanish and intresting with its lovely harbour and old buildings. My 12 year old daughter loved it their and the shops to as some of the shops are built in the rocks of the harbour.
