We did the 89 night Grand Asia last fall...it was magical and I cried the last 3 days saying good-bye to all the wonderful "kids" who became like family. Mail was forwarded to our daughter, voted before we left, and had our master bath redone while we were gone so had, trusted, people in and out of our house the whole time.
Just be sure you have all your daily "stuff"...meds, eye-drops, moisturizer, etc. with you.
I packed 25 thin felted hangers and had our stewards remove the big wooden ones, made a huge difference in closet space.
We took full advantage of all the dining options, loved lunch at the Pinnacle and Sunday Brunch at sea in the MDR. Never got bored with the food, did lots of room service. We both actually lost a little weight because of all the walking we did.
Enjoy..it's addicting.
