Are there glasses (cups) or wine glasses in the room? (Mariner of the Seas) Ice bucket? Do you get your own ice or does your room steward? Will your room steward empty out the fridge so you can fit your own stuff in?
We were on Radiance. There was always fresh soap, the shampoo/conditioner was full (basic stuff). A hairdryer. I have short hair but it is thick but it did the job. Glasses in the bathroom & @ the dressing table so we had enough for water & for our drinks. Always freshed up. Always had ice when we came to our room after they made the room up & always fresh ice @ nite. They will get you more if you want it - just call them & get they get it pretty fast. We had the basics plus 2 beach towels plus extra beach towels everytime they made our "towel animals" on our bed. We had extra pillows & blankets w/o asking for them. They will empty the fridge for you if you want. We had room in ours even before hand but they will empty it out if you ask.
