I was in and out of the Aruba cruise ship dock area in May/June last year (I work on survey boats). Didn't have mavic with me but I did notice that the wind was a fairly constant 30-40kmh all the time I was there, blowing to the south (out to sea). So something to keep an eye on. Also, the marine police HQ is about 50m from the quayside you'll be docking at, and security is pretty tight around the port. They may have something to say about flying around the area if you're spotted, although the island in general is super-chill so I'd be surprised if they did more than come over and ask you to stop if they do object.
You'll also be just a couple of kilometres from the airport.
If you come out of the port and turn left (heading northwest, opposite direction to airport), walk about a half hour up the road you'll find Eagle Beach which is gorgeous and some very pretty hotels. It's like a mini Vegas around there. That would be my pick for some quick and easy flying.
Toward the centre of the island there's a national park with a mountain/volcano thing in the middle of it. Great flying opportunity, but you'd need to rent a vehicle to get there.
Best place to eat/drink by far is here in the town centre.

Not least because of the friendly waitresses. And I DO mean friendly!!
English/Dutch/Spanish is widely spoken by the locals. The locals also speak "Papiamento" unique to the island. Download an app, learn a couple of fun phrases to use and you'll do well.
Aruba is amazing. I'm so going back one day.
Have fun.
