We are starting the Camino in mid-April and would like to stop along the way and take a day off every now and then to get some rest, do a little sightseeing, etc. We are thinking we'll probably stop at the cities of Pamplona, Burgos and Leon. Any other recommendations for where to stop and stay? Also, what sites to see and what restaurants to visit? Will it be necessary this year to reserve a room in advance? We will be as flexible as we can be. Our only constraint is that we need to meet my teenage son in Sarria so he can join us for the last leg of the walk. He will be arriving from Barcelona in mid-May. Thanks for your help!
