DCL has made some cutbacks over the years -- even though I'm old, I think that I remember that on the Classic Ships there used to be about a dozen cruise staff onboard running activities. I think that they are down to about 8 now. That makes a difference - but people must not have noticed.
On the other hand, guests noticed when DCL stopped giving out "Sleepy Chocolates". At 50 cents per room for crappy chocolates, returning guests were up in arms and DCL reinstated the chocolates (and it cost them at most $400 / day)
They have dropped the "Live Bands" onboard because they weren't bringing people into Fathoms / Wavebands / Evolution / The Tube at night in large enough numbers so they changed over to DJ's. Pay for only one person - much less expensive and the same 12 people per night show up. Like I said earlier, I'm old so i found the live bands AND the DJ"s way to loud. I've enjoyed the various bands in the past for the few minutes before the nightly show and right afterwards - always a bunch of talented people, but I didn't like my ears bleeding. blah, blah blah and "no one" complained, so DCL continues with this "cut".
These are just a couple of examples of cuts. There's probably many, many others that DCL has made over the years. And they WILL continue to make cuts, and only by enough guests making comments on their cards at the end of the cruise will positive changes happen.
Off the Soapbox now.
