We spent over a week in Curacao in 2007.
There is really no night life on West end.
Seriously true, we found that out also. It was hard to find a bar in that area. Or anything open much after 9pm.
An option in
west Willemsted to consider:
Piscadera Bay Resort.
It's located in Piscadera Bay, a resort/convention area. Although they're probably bigger than you need at 2BR's they're also $103/nt. Plus a one time cleaning chg. It's a quiet/gated complex with parking at each unit. A/C in the bedrooms only as is the style in the N.A.
They're older but recently refurbished, all three that my group rented had 4 burner cooktops and microwaves, full size refrigerators and indoor/outdoor eating spaces. But none had an oven. My friends had the best of the three, #4 as I recall, it had ocean views. A couple have pools but I don't think they rent those. My unit had about 1/2 US electric plugs also - something we hadn't considered.
A local dive/beach bar - Hooks Hut - is 2mins. away. The diveshop picture on the PBR website above was shot there. The Marriott and the Hilton are just down the street, both have outdoor bars, indoor bars, pool bars and small Casinos, the Marriott had an outdoor party on Friday on the beach somewhere. (maybe other nights but we heard it on Fri)
Piscadera Bay got pretty quiet at night. There's a couple other resorts/restaurants in the area but everything else is a short drive downtown - about a 10-15 min drive. It's also about a 20 min drive to some very good diving west of town or 20 mins. east to the SeaAquarium area - a more touristy part of Willemsted. The closest market is a mile or so back towards the airport. It's called Centrum, you'll pass it on the right driving from the airport to PB.
You won't get into Lions Dive for less than about $175/nt. we looked at it also. And it's $75 more if you go AI there. My guess would be that anything in that area is similarly priced. Too much for us...
hth,
