The diving on the island is in two different areas. South of town on the reefs and a few wrecks there.... then off Palm Beach area, near the high-rises.
Dive Boats depart from either location to the other. So it doesn't matter which
you stay in based on a boat trip.
All dive ops pretty much have free pick up and drop off service also.
Besides the ones mentioned above, the Holiday Inn is on the high rise
area and is more economical than the Hyatt or Radison, but it is
a Holiday Inn also, so there is a difference. (but they do have a
good onsite dive op - Pelican).
Down betwen the Radison and the Aruba Grand is "I think" the Unique
divesports group. I know some people who used them and liked them.
the Radison and Hyatt are very nice. you can't go wrong.
The Marriott is nice also and you can't go wrong, but you might
get some contruction noise if they are still building around it.
check into that.
The Wyndham is nice (we stayed there) but I will have to say
that I've never stayed at such a nice place that had a bar
and bar service that sucked so bad. But everything else was
great.
The Renaissance is nice, but it's "in town" and some people don't like
that. It's on the "main drag" and you get a lot of traffic and
traffic noise. It's actually seperate buildings. One is in town
and across from the harbor and not on the beach, but they have
a water shuttle that goes to their private island which is right across
the way. Then they have some units that are on the water and have
a nice pool also.... but not much of a beach. But you also have access
to their private island area for that. I think that Red Sail is the
onsite dive operator at the Renaissance, but most people don't
prefer them as they have the reputation as being a cattle boat on the
island and cater also to the cruise boat lines. If I was staying at
this hotel, I'd opt for Dive Aruba as he's in the same marina and
has a much better reputation.
If I was staying up in the High Rise area, I'd use Pelican, Dive Aruba
or Unique.
