Reykjavik Hop on hop off

I saw some statistics recently that showed that the number of tourists in Iceland from 2010-2015 have increased by 264%, that is mind boggling. We do see its effect, English is spoken everywhere (making me feel less like an outcast!), and one has to book 8 months or more ahead to find somewhere nice to stay if you are travelling anywhere, to name just a few of the many side effects. Another one is that there is now a Reykjavik Hop on hop off bus...I do like the pictures on it, I don't like birds, but love puffins!
