Can any recommend a good tour company for the Golden Circle/day tours and give idea of what kind of prices to pay per person based on own experience and best way to transfer from airport etc or any other tours they'd recommend. We are there for 5 days, first visit, really don't want to hire a car, keen to see (even if cliche!) key sites to get a taster and would love to hear any other tips, suggestions to make most of our trip. Going in January, staying in self catering apartment. Thanks!
