We bring -
laundry detergent
coffee
coffee filters
sugar
salt and pepper
and any other food we want - those sorts of things (coffee filters) aren't in the DVC resorts (you get a starter pack of coffee).
If we have a kitchen, we will order from Garden Grocer - generally food for breakfast, beverages, and a few snacks. We do most of our eating in the parks.
The grocery stores have a really limited stock at convenience store prices - but they aren't bad if what you want is a dozen eggs, some milk, and aren't picky about your cereal.
Storm Along Bay is really cool - but there is a window in time where for some parents its a nightmare - its impossible to see the whole pool from one point - so if you have multiple kids that you need to keep an eye on, but are old enough to want to be independent, it can be very stressful. Once they got past that point, my kids wanted the waterparks over SAB.
