We went on a CUDO Deal. 7 nights accomodation including daily breakfast + airport transfers + a half day island tour was $285 for 2 people.
We booked the flight through Qantas & used points.
The car was $35/day + fuel (fuel is $2.41 / L)
Only other cost was dinners & organised tours.
For 2 of us the week cost a total of $1325. That includes EVERYTHING. Spending money, & gifts. The lot.......
As has been said, it's a magnificent place. The speed limit island wide is 50klm/hr, you don't have to wear a seatbelt & the cows have right-of-way.
Everyone is extremely friendly & helpful. Some of the cliff-top homes have spectacular views.
Very much a place that I could see myslf loving.
