Syntax error? I cannot figure out where it is?

I'm just overwhelmed. This statement has a syntax error highlighted at the colon after the 8 in the first if statement and when I delete the color, it highlights print. I am referencing this code from another one almost identical to one I know works. But even copying and pasting the if statements from the old code I am getting a syntax error. Where is it? How am I missing it

print("Hello, and welcome to our program!" + \
      "Follow the prompts below to begin" + \
      "planning your vacation.")

# Ask about the number of guests
party = int(input("With how many people will you be traveling?" + \
                  "(Larger groups may qualify for a discount!)")

# Display discount
if 5 < party <= 8:
    print("Cool! Your selection qualifies for a 10% discount" + \
          "that will be applied at the end.")
elif 9 <= party:
    print("Cool! Your selection qualifies for a 30% discount" + \
          "that will be applied at the end.")
elif party < 5:
    print("Sorry, your purchase does not qualify for a discount.")
