the go it alone tickets cannot fault service or value, wanted to be self led rather than rushed around, BUT we still did not see everything we wanted, advice would be be prepared, have drinks and food, options inside limited, and outside cost super expensive £10 euros for two frozen lemon drinks. and have a guide book as the site on only gives numbers no names. Or if you can do two days maybe one as a tour and one taking your time to explore the outsides edges of site as these we amazing.
