Friends Flaked on Me. Thinking of going to Iceland solo. Yay or Nay?

I had planned out a trip with some friends (in the states) and already requested the time off work. My friends are starting to sound like they wanna flake cause they can't afford to go anymore. I have always wanted to see Iceland, but I'm a little scared about going solo. Will an awkward dude from the States stand out? Do people generally speak English? Anyone want to hang out. I was thinking of going from the 19-26th of this month.
