There is a typo in the Title of this exercise

Could it be that "Sun7" is a cute abbreviation of "sun-se(p)t"?

Craig, according to their Facebook page, and Trip Advisor, this bar on Marie-Galante island is indeed called Sun 7 Beach. As Chris said it was probably named as a pun. Hint: it is usually best to check your facts before criticising, in my opinion.

Paul, I'm sorry you thought I was being critical. The content of these exercises are fictional, and I had no idea there was actually a beach by this name, but there are countless "Sunset Beaches" in the US.  So I was simply trying to point out what I thought was a typo to the editors of the program so it could be fixed. I'm hurt that you implied I was being rude, when I was just trying to be helpful. I'm new to these exercises, and don't know how else do so. 

Craig - For what it's worth, I didn't get it either and wrote "Sunset Beach" in the dictation. Only after I saw the hint, (which I had not noticed), did I realize that it was a pun on the word "sept=7". So, you aren't the only one.

I often ask about things in the exercises that I believe are “wrong”, and it’s then explained to me that in fact I’m the one who is wrong, and I learn something new. This is a great way to learn and I  recommend it. The alternative is to not ask for fear of being mistaken, which has a chilling effect on learning. 

I thnk the alternative is always Google :) I just Googled "Sun7" and it came up immediately. When in doubt, Google! I was pleased to see this place and was amazed at it and had never heard of it before. The next thing I googled was flights to Marie-Galante ha ha ha
