It does seem like an overall improvement for people but there are winners and losers
On the face of it, the drinks package seems a slight improvement. I think it depends on what this "Connoisseur Collection". If you aren't fussy on your brands, I suspect you'll do well, but if you drink a lot of the absolute top shelf stuff, it will now cost you more. I'm pleased that I'll get the MAS drink benefits for my FAS booking in Feb.
Specialty dinning seems an improvement, extra meals, extra starters/desserts
Wifi is a downgrade from me. The only winners are the cabins with 3 & 4 guests on shorter cruisers. I'm a solo on a 12 night cruise and thankfully on FAS I get 300 mins, but on MAS I would only get 150 mins. I think measuring internet in mins is just silly anyway, it should be in GBs. I don't see why if you're waiting for someone to reply on WhatsApp, it should cost you. It would be so much more convenient to just leave your phone on all the time and use your data when you want.
