Hmm, it doesn't seem like it, although there may be TA content that is being blocked by my ad blockers.
The links to book individual sailings (once you drill down to them) don't even seem to contain any referral codes. Well, at least not on the first cruseline/sailing I clicked. (If the cruiselines even gives kickbacks for the click itself, and if that's even something worth banning.

)
Edit: I turned off my ad-blocked and I still only see typical travel banner ads, including ads that go directly to
RCCL. Kept refreshing, got an ad that went directly to Princess.
(Note: I am not being argumentative with you personally, I just find the information barriers inherent to travel forums to be particularly arbitrary and irksome. CC, for example, automatically filters out any links to imgur, a common image hosting site. No idea what that's about.)
FINAL EDIT: Maybe it CAN be mentioned here, just caught up. Maybe it's CC where that one is banned too. Sigh. Sorry.
