I would change things a little, Leave Blue Red and Gold as is, then with Plats, Get rid of priority Boarding, but keep early check in, Get rid of the Past guest party Get rid of the 1 drink per person Durring Sea day brunch, and give 2 or 3 vouchers for a free drink of there choice per day. Add Plat + and add 1 free specilty dining on 5+ day saiings, or Steakhouse Selection on ships w/o specialty dining also 4 free drinks per day. Dimond would stay the same except 2 specilty dining and 5 free drinks, and Dimond + would be 3 specialty dining, and 6 free drinks per day, and special Lunch with the captian. JMHO on what should be done.
