How much would a whole week cost to be here

It varies on when you plan on visiting and what kind of room you want. Go look on their website.

The high season starts in January and goes until April.

It's pricey, luxury hotel, maybe right now it's not so expensive, it's not a high season for them

Check any hotel site online

You pay for what you get. Other wise theres more affordable options.

Varies on time of year, type of room etc. Worth it though!

I don't know because we went on points with Marriott. I heard the rooms can run $200/day. But it is worth it.
