HELP! Question about electrical plugs on MAASDAM

Ok, so I am aware that the electrical plugs on all of HAL's ships are the US kind of plugs. HOWEVER, are they the two prong plugs or do they have the 3 prong grounded plugs? We need to know if we need to bring an adapter for our cruise in January! Thanks everyone!

Three prong with one of the flat pins wider than the other.

Thanks for your quick response! Good to know!

Also have 2 pin plugs which we used for charging cell phones,razor etc.

I'm not certain, but I think that Maasdam has a Euro-style 220V outlet next to the US outlet on the desk. So, a tip -- you can use it to charge a dual-voltage phone etc if you bring a Euro-to-US adapter plug. Also - there is only one US outlet, but you can plug in a "cube tap" (3-way adapter) and plug in a couple of items. Another note - there is a dual voltage outlet in the light fixture in the bathroom, but it shuts off when the light is off so it is no good for a night-light.

One other thing--I'm pretty sure the Euro and US outlets are right next to each other so you can use both outlets OR a 3-way tap, but the 3-way tap will preclude access to the other outlet.

I find I can keep the bathroom light on and keep the door closed at night and it works fine for me.
