If you're familiar with SXM, Aruba is quite a bit different. Aruba is more 'Americanized' than SXM. There are a lot of chain restaurants there. Overall, it is cleaner than SXM and probably safer. Prices in general for food in the grocery store and for booze are higher. There is a good bus system and you don't actually have to rent a car there, and can get around fine without it. I have no idea about Uber, as it wasn't available the last time I went to Aruba, but frankly I would never do that anywhere, but that's just me. There are lots of timeshares there, and lots of rentals also. The scenery is not nearly as pretty as SXM, as it is very desert-like, with no green hills like SXM, and in fact, basically no hills at all. The wind blows there fairly constantly. If you haven't been before, it's good to try out.
