Hopefully this isn't a dumb question, but here goes.
I'm staying at BBGE in early April and I've heard most of the staff speak English but I'd also like to brush up on my Spanish in case it helps. It's been years since I've spoken it for any reason so there are only a few phrases I can remember - mostly the obvious. Hola, gracias, buenos dias / noches, por favor, donde esta..., agua, toalla (towel), etc.
Are there any other phrases I should learn that could come in handy? Do they say 'bano' or 'servicio' for restroom?
