I don't know what you could do better!
My one tip would be to BOOK EARLY. I started browsing 3 months out, but forgot to order until a week before our trip and there was only ONE delivery date left. We still got our stuff, but it was on day 3 of 8!
Your service was fantastic! From the confirmation phone call (before our trip) to the notification phone call when the food arrived at our resort ->you gave me peace of mind and relief that I would have "secondary food" readily available during our vacation! THANK YOU!
