Ibiza

I had an amazing time when I went to Ibiza but it definitely did me dirty.  A group of us went to Ibiza one weekend at stayed at Hostel Florencia.  It's located within a 10 minute walk from the beach and a little ways away from the city center where all the clubs and bars are.  However, they do provide transportation to the center.  The beaches are great so you can tan all day.  Once you're done tanning, get yourself ready for a crazy night.  The first night we went on a bar crawl through the bars that are closer to the hostel.  The next night we went to the original Pacha club.  The entrance fees to the clubs are expensive but you can save some money if you buy special event tickets earlier online.  Ibiza the main party island out of the Balearic Islands so only come here if you're looking for just that.  

Palma de Mallorca

My trip to Palma de Mallorca was a lot different than my trip to Ibiza.  Instead of a hostel, we decided to stay at an AirBnB.  Our host was Tony who made sure we knew how to get to the apartment right when we got off the plane.  His apartment was nice and close the city center.  The main square has Le Seu Cathedral and is next to a lot of stores.  When I went, there was a huge beer festival that was situated right in the center.  You can also take a number of buses to get to any of the beaches.
