Per our policy at Kalahari Resorts, we do not accept completed Letters of Authorization forms, Tax Exemption forms, nor Purchase Orders to be submitted to us at the hotel check-in. We have a dedicated team that approves these forms to ensure validity prior to attachment to the reservations prior to check-in. These forms should be submitted no later than 7 days in advanced to us at dellscallcenterfax@kalahariresorts.com or fax them to 608-254-6116. We highly suggest that attendees submit these forms at minimum two weeks in advanced prior to the hotel check in so our team can process them in a timely manner. Failure to follow this procedure may result in full room and tax charges to the attendees on their personal cards; since our Front Desk will not accept these forms at check-in. Questions, go to our website that will bring you to our general policy page for the entire resort, which explains our policies in full detail.
