I was on the Granduer for Christmas just last year. The only difference is that last year RCCL offered 2 week long cruises over the holidays, when this year it was 1 12-day cruise over both Christmas and New Years. Compared to last year:
1. Qualtiy of food drastically went down.
2. Dinner menue selections were repetitive.
I did not take a tour, but this site would not let me continure to the next section without filling in.
