Hopefully you will get a response but generally (and you should consult with a tax export) donations of a one time use at a timeshare or any other property is non tax deductible. See example 2 below.
This is from IRS pub 526 "Partial Interest in Property
Generally, you cannot deduct a charitable contribution of less than your entire interest in property. Right to use property. A contribution of the right to use property is a contribution of less than your entire interest in that property and is not deductible.
Example 1. You own a 10 story office building and donate rent free use of the top floor to a charitable organization. Because you still own the building, you have contributed a partial interest in the property and cannot take a deduction for the contribution.
Example 2. Mandy White owns a vacation home at the beach that she sometimes rents to others. For a fundraising auction at her church, she donated the right to use the vacation home for 1 week. At the auction, the church received and accepted a bid from Lauren Green equal to the fair rental value of the home for 1 week. Mandy cannot claim a deduction because of the partial interest rule. Lauren cannot claim a de duction either, because she received a benefit equal to the amount of her payment. See Con tributions From Which You Benefit, earlier."
