Hey There and Welcome to the Forum.
Like everyone else said before, you will need to have accommodations arranged/confirmed before arrival on Aruba. Immigration is very strict about that when it comes to visitors to Aruba. They will ask for it on your immigration card and they will ask you again in the immigration hall.
With regards to accommodations MVC Eagle Beach is a good option, you may want to check out the Little Boardwalk Hotel, they are situated in the Palm Beach Area. Or the Aruba Beach Villas is another option. As you're aiming to visit around late November/early December it may be a bit tricky as it's the beginning of the high season on Aruba. And you may have to stay at a hotel that is not on or within close proximity to the beach. If you are renting a car it will help. Still check around on the various hotel sites, something is bound to pop up.
Hope that you enjoy your first of many visits to Aruba.
