How many counselors there are really depends on your little cruiser's ages.. There are usually 3 counselors to each of the teen areas (6 total). Then about 20 or so between the Lab & the Club. Then the nursery usually has 6-8ish.
Candy is a great tip for your YACs (Youth Activities Counselors). Some of the best "tips" we've received came from guests that would wrap up uneaten portions of their meals & bring them to us. We don't really get to eat guest food more than once or twice a contract. One set of parents brought us a pizza from Palo & it was AMAZING! Went so fast too! Another time a dad ended up sending his daughters up to the club with plates of goodies from a midnight dessert buffet. AWESOMENESS!!
The BIGGEST tip you could EVER give your YAC is to write into
DCL specifically naming counselors. This will go so far & the YAC will get instant recognition & the letter will go into their file.
