secondary communication point symbols

I created my symbols on Illustrator. Originally my three communication points were going to be: wind exposure, amount of seating available and whether there are public toilets available. Before I started drawing up my symbols I re-evaluated my communication points and decided to change the seating available symbol to amount of shade available. I made this decision because all three locations had lots of seating available which is a given for any site being recommended for eating your lunch in. I felt as though shade available would be more useful to potential brochure users.
