We arrive at Disney on Wednesday so I have not experienced picking up the water from the front desk, but I did just order our water from Costco based on info and facts that were posted here.
1. You do not have to be a member of Costco to order items from the, we are not members and there was no problem whatsoever - we just did it online.
2. Address it to yourself, checking in on xxxx date, hotel name and address. I have read the hotel will hold it for 5 days. We ordered it on Sun for a Wed arrival in hopes that it will be there when we arrive.
3. A case of 24 (16 oz) bottles was $6.98 + tax, delivery is/was included in the price.
A lot of people order from Staples, but there was a charge for delivery so that's why we went with Costco. We saved $6-7 by doing so.
Being August I'm sure we'll go through that one case very quickly, but it's just a short trip so we did not want to waste any bottles by ordering a 2nd case and we can always buy it onsite if we run out.
