Olbia/Dorgali

Hi everyone. I booked 3 nights for an Airbnb in Dorgali and 2 in Olbia. I’m interested in also visiting the La Maddalena islands, but not sure if it worth having to pack and move to a new location vs staying in the same spot. On a recent post, people assured me that there is so much to do around Dorgali. We are planning on doing one boat day and one hike day to Cala Goloritze. I want to be able to see pretty beaches that are also very accessible and have towns nearby with great food and wine. Does anyone have an opinion? Should I stay in the one location or switch it up in order to see La Maddalena? I hate the stress of packing and going to a new place, but also want to make sure I see the best during my trip! Thank you :)
