Wanting to plan a break from the winter weather, we got a very good deal on an inside cabin on Grandeur. We've sailed on the Lady G before (Sept. 2018 NE/Canada) and knew what to expect. Me (53), Husband (57). Our neighbors also went and this was their first cruise.
We got emails prior to departure that the ship would go through extra sanitizing so do not arrive before noon. We arrived a little after noon due to traffic just before the terminal. Then we waited outside in a line to get into the terminal. It was quite cold, so it would have been nice if the first check in point could have been inside the doors instead of right at the door. The line moved very slowly at first, then picked up the pace. I found out from others that they were actually allowed to board just after 11, so was a bit disappointed that we delayed our arrival, but I'm a rule follower!
Check in was very easy after that, and we went to the Windjammer for lunch. It was very crowded, but the food was good. Cabins were ready at 2pm (as opposed to the typical 1pm.--another result of the extra sanitation efforts.)
The cabin is small, but space is efficient. If you're on a longer cruise with lots of hanging clothes, you may need a few extra hangers. You should have plenty of storage space if you use your space wisely. Use hook magnets on walls to hang hats/jackets, etc. to help organize.
There is plenty to do without buying excursions. However, if there's an excursion you want to do, keep checking prices. They seemed to fluctuate quite a bit!
