Easiest to start with the third - we all know there's a mandate to integrate IP and branded storytelling across the property. Do I agree with it? No, but it's happening regardless.
Taking that into consideration, this is clearly a best-case outcome, as Mary Poppins is an IP that many consider appropriate for GF, and if you can't stand the tie-ins, it's not blatant at all.
To those who aren't specifically looking for IP (myself included), the new design appears to take inspiration from other colors and motifs already present throughout GF. I also disagree that the execution is poor, that's a matter of opinion. Neither one of us is alone, but is there a single instance of interior design that appeals to everyone? Not that I can think of. Even Poly, WL, and AKL have their detractors who'd rather be somewhere like GF or Yacht Club.
