This is an Ina Garten recipe we love, but serving it an an open house party that lasts 3 hours.
Just curious: does anyone know if Ina has a Q&A for her own recipes?
teridawn, for a recipe with cream or cheese, 2 hours at room temperature. Then get it back in a fridge with that is not over-loaded for 30 minutes or so. If there is not fridge, and the dish is important to the event, return it to closed coolers with ice.
I'd give anything to be able to edit posts here.

You need to be able to maintain it at a temperature of 135 degrees. Have you thought about using a disposable chafer in which to serve them? I know Sam's club sells them, and likely other places as well. Alternatively, keep them warm in the kitchen, only putting out smallish amounts at a time.
