There are many subtle ways to reward frequent cruisers, without offending those who cruise less frequently or first time cruisers. To be edged out of dining opportunities, etc. to make way for more frequent cruisers would be very bad business and, quite honestly, insulting.
RSSC's objective should be one of enticing a less frequent cruiser to become a more frequent cruiser. Class distinction won't accomplish this. Anyone who takes a Radisson cruise should never be put in a situation of "experience disadvantage."
