Everything. Truly everything. We provide luxury bamboo linens on all beds, towels for bathroom use, towels for pool use, towels for beach use, 10 adult beach cruisers, 4 children's bicycles, a carrier for the littlest tikes. We have propane for the massive Weber gas grill, unlimited heating for the pool and hot-tub, air-conditioning in each of the bedrooms. You'll have toilet paper, paper towels, hand-soap, body soap, shampoo and conditioner. The kitchen is fully stocked with standards like place settings for 14 people (including kidsware), a blender, toaster, instant pot, waffle maker, electric griddle, coffee bean grinder and a mandolin. This isn't the exhaustive list, but we've continued to add things over the years to make Windows on the Sea truly a home away from home for ourselves and our guests.
