Sounds like we already have a terrific group sailing on the Grand 5/20. We all should meet in the wheelhouse bar (everyone has good things to say about this bar) and say Hi.
This is our 2nd Princess cruise & first on the Grand.
As far as location on the ship. We have sailed 15 times and we prefer mid deck/mid ship. Since this ship is so,large & stable I think it may not be much different from one area to another.
We sailed on the Voyager (2/00) and found to be like sitting in our living room...no movement (Grand is smaller).
The rear/lower decks of the ship are the most stable, which is why the diningrooms are always in this spot!
We decided to do an AC cat (AB & AA were waitlisted) & mainly because this cat was discounted and we really wanted a minisuite w/balcony. Maybe we will be upgraded to a suite! Who knows.
As far as inside/outside...here's my take on this...cabins in both are the same size & same ammenities only difference is a window....big deal...if you are not claustraphobic you will not care EXCEPT if daylight is a must. We actually sleep much better in an inside cabin. The addition of the balcony is terrific for privacy & a guaranteed lounge chair in the sun! Since we have our 19 year old son with us the suite makes it comfortable....ALTHOUGH we feel OK in an inside cabin as well....especially when you want to do a lot of excursions...the difference in price from inside cabin to outside w/balcony can pay for all your excursions & bartab!
Try all catagories and see which one makes you the happiest then keep cruising!!!!! Can't wait to meet all of you!
