For those who have made their decision, I would recommend reserving a hotel room for move in weekend and move out day as soon as possible. Students move into their dorms before orientation which is usually one week before classes start. Orientation dates should be posted any day now. Students need to be out of the dorms 24 hours after their last final, or no later than June 12 (even if their final is that day).
Davis has a parent/family weekend in the fall. It is a good time to visit your Aggie and let them show you around their new home. The big community open house is Picnic Day. It is held every year in April. If you plan on going, keep your eyes open for when they announce the dates so that you can book a hotel ASAP.
For students who may be flying home, Southwest already has flights available through Jan 6, 2025. That means you can book both Thanksgiving and winter break flights now. I would recommend booking Thanksgiving flights ASAP. UC Davis has classes M-W of Thanksgiving week and Th & Fri off. You can find the academic calendar here.
