For those who take seriously the recommendation to have the seder in the afternoon at 2 or 3 pm on zoom with the grandparents, it is worth remembering that it is absolutely forbidden to eat matza on Erev Pesach. So it will be a seder without matza [וכל האוכל מצה בע"פ כאילו בא על ארוסתו בבית חמיו - ירושלמי]. One is allowed to have meat, fish, salad, cheese, eggs, horseradish, fruits, vegetables, and potato starch cakes. However, one should not fill up on these items so as to ensure a hearty appetite at the seder. He may drink wine or grape juice on Erev Pesach in quantities that will not affect his appetite at night.
To have the main seder during the day and just do a quick one at night is actually a tremendous זלזול to the seder. This is not Thanksgiving, where it is just a nice time for family to get together. This is a one time a year mitzva from which we are supposed to draw Emunah and inspiration the entire year.
So how about this suggestion - call up the grandparents before Yuntiv, tell them how much you love and miss them, ask them for presents and money the four questions, share a few vorts, wash your hands, tell them again you love them, sing a few hagada songs with them, wash your hands, tell them you love them again and that you will miss them - then hang up, wash your hands and get ready for the seder. They have been through a LOT in their lives. They will make it through this one, too....
