Hi Deb.
I can suggest either...Saville Park Suites on the Esplanade, Holiday Inn on the Esplanade or the Atrium Hotel also located there. It really depends on what your budget is and I would not leave it too late to decide as accommodation is pretty tight everywhere. All the hotels on the esplanade face the ocean to the north, but the Holiday Inn (
previously the Travel Lodge hotel) gives you the choice of a balcony and either view which ever side you wish of Darwin.
Personally, I'd stay at the Holiday Inn
http://www.ichotelsgroup.com/h/d/hi/160/en/hd/drwte simply for its convenience and choice of
balcony views north, east, south and west!
Novotel Atrium - nice but no balconies
http://www.accorhotels.com.au/Novotel-DarwinStorms come from just about anywhere and depends much on dominant winds. It's a bit too involved for this particular thread so I'll PM you with some details on what's in store for you weather wise. Photographic ops really depend on where you are but the wharf is about perfect and only 15 mins walking from your hotel on the Esplanade - or 30 mins in 200% humidity!
Give me a call when you arrive and I'll definitely catch up.
