If its a few items, your best bet is to:
1) Buy bottled water at the resort - they sell cases - it will be convenience store pricing - but that is what Hess is
2) Pack the snacks down with you. Unless you are planning on checking no bags and have full carryons - slipping some granola bars and Pringles into your suitcase should be doable (bags of chips do take up a lot of space).
3) Buy some supplemental snacks (the bags of chips) at the resort.
If you are talking about more than that - a Garden Grocer order. If you are not at a convention hotel, you can order through Costco or Amazon and have it delivered to the resort - they will hold it until arrival (a convention hotel will have a charge on delivering and holding a package - but I don't think the other hotels do).
