Yes, Lil Suckers work! They will keep the drink upright.
They won't keep it cold, so if you're in a temperate environment, perfect.
In California where the water is cold, I use the water and tow the water bottles behind me. It's not too much drag. You can tie them one by one or use a fish bag.
In Florida, I use a soft waterproof cooler, small blue ice packs and pick which is cooler - water or air. If it's air, I wet a white towel to reflect the sun and provide a little more insulation. Sometimes I make it wear a hat!
