A couple of comments here
1. My understanding from the mom of an alumni is that there is a graduation ceremony, but it is only for the CP graduates. Parents cannot attend.
2. I did get my DS all settled in for his program this week. Check in was on Monday, and he left the Holiday Inn at 7:15am(with all his roommates, who had all stayed there) and walked to 8am check in. The students arriving were divided into several groups, and my son's group had a 10:30 bus to Casting. He was finished there (and for the day) and back to Vista Way at around 1:30pm. We went to lunch and shopping at Walmart and had plenty of time for getting him settled in his apartment.
3. On his 2nd day, everyone has a meeting at 10:45. My understanding is that it does not last too long, but if you are counting on your child driving you to the airport on day 2 I'd recommend an early morning or late afternoon flight.
4. I am pretty sure he (and all the roomies) are free on Day 3. If you want to spend a day with your child when they don't have any conflicts you will need to stay through this day. They do not receive their park passes (for themselves) until Traditions, so if you'd want to spend a day together in the parks you'd have to pay for your child this day.
5. Traditions is on Thursday. I am not sure how much time that takes since it hasn't yet happened. My son has actual work on Friday (although his roommates are completely free that day).
Hope this helps other parents trying to plan hotel stays/flight times! I think, if I could plan in hindsight, I would have scheduled my flight back on Thurs rather than Tues. I might have considered changing hotels after Monday, too, because the Holiday Inn is not the cheapest place to stay and has a pretty rotten location, traffic-wise. It was a very pleasant place to stay and is wonderfully convenient for the CP check-in, but after that process is done there is just plain too much traffic to pick this location over the thousands of other hotels in the city.
