Tuanis laundry right down the street, next to Power Wheels Adventures ATV Tours will pick up and deliver your laundry at process much cheaper than the hotel laundry service. They have a website tuanislaundry I can't write it her as TripAdvisor won't allow hyperlinks.
Hey, great answer about the pool! And I am sure reception can point me to where I need to be.
I have no idea. You have to arrange this in reception. I think you can pack "dirty laundry" and bring to reception ladies. They will sort it out...
I had a room without laundry machine, but I am sure they can fix your problem.
You can also go to the swimming pool, during the night and fix your problem yourself ;-)
