When you are planning to depart, empty all the under counter refrigerators and combine the contents into one fridge, if possible. Or empty the refrigerators entirely if there are only a few items remaining. It's is cheaper to replace a few remaining grocery items then to pay to leave the refrigerators turned on for just a few items.
When you are departing, set your pool and spa run times to "away mode". This is the best setting for when the home is vacant and provides just enough power to clean the pool and spa without unnecessary run time. As an alternative, you could have variable speed pumps installed that can be adjusted to maximize efficiency based on occupancy. There would be an initial cost, but the savings would recoup the cost in approximately 8-12 months based on occupancy.
