As a family we have been going to Puerto Pollensa in Majorca for the last 15 years and every year enjoy it more and more. One thing I would recommend is that you book bus transfer from Palma airport beforehand, as a taxi from the airport can be quite expensive.
Perfectly true - Puerto Polenca is wonderful. Ideal for children as the tiny bays along the Pine Walk are very shallow. As for airport transfer, my hotel (The Miramar 1st Class) arranged a return taxi for €140 which doesn't work out so bad if there are a few of you.
