We would recommend staying around the Puerto Pollenca area as it's on the sea, you get the sea breeze, and it will be where the majority of others are staying. There are lots of lovely places to stay in the area, a lot of which can probably be done more justice on Tripadviser than us!
There is a lovely front on the sea with lots of bars and restaurants to choose from, and a lovely public beach to get your pre wedding tan if needed.
Hotels that we have stayed at and recommend :
Uysal/ Hoposa - there are two nice hotels which are based in Puerto Pollensa, run by the same group.
We can also recommend Marsenses (https://g.page/marsenses-puertopollensa?share), which has a nice pool and cocktails, with a good breakfast.
Pollenca old town is also a great place to stay. This is 15 mins inland from Puerto pollenca. It’s a very pretty historic town with a beautiful square in the middle. There are lots of shops, bars and restaurants to visit.
There are lots of private villas available in the area if you have a look on Airbnb.
Son Brull - this is just on the outskirts of Pollenca old town. This a lovely hotel, with a fantastic resturant and spa.
Mon hotel - this is in Pollenca old town - this is a great hotel if you would like to stay in the center of the town. It’s right in the mixer and easy to walk to all places from here.
