Traveling with my Irish family. They are looking for a Golden Circle tour that will allow the freedom to stop and eat and have some pints during the day. Possible?
Contact any of the highly rated operators under Things to Do at the top of the page and they will happily tailor-make a private tour for you.
Not sure about the availability of pints on the GC route (alcohol is very expensive in Iceland, just like everything else), but the operators should be able to tell you.
Just to confirm what Kim said - many tour operators do offer private tours that can cater to your needs. However, getting alcohol on the way might be a bit problematic, albeit not impossible :)
Maybe they could bring some frosty beverages along with them?
