Gig recs and financials

Hi!! I was just wondering if going to italy on GIG costs more than the other countries or if it is still the same price, which is the traditional 'unit fees'? And just to clarify, they cover flights, accommodation and transport? I know italy is competitive, but i want to know if it is worth it!

Also if you went on gig, how was it? Which country would you recommend based on the activities? I'm thinking italy or Vanuatu!
