@Stockpot firstly, congratulations!
Could you send your DC with clothes and sporting stuff early then rock up later with all the other stuff students need in time for freshers? I'm sure the sports captains will be able to help with solutions.
We found DD's college was really helpful about drop-off/pick up times due to the distance. My record time from home to college was 3hrs 40 with no stops; the longest is well over 7 hours, so we could never be sure of when we would arrive.
For Freshers we ended up taking 2 cars. Mine had both DDs in it plus all DD1's clothes, books, shoes (dear Lord, the shoes!), bedding, crockery, cooking stuff and whatever else. My car is used to transporting large musical instruments around, so is good for this. DH took DD's bike as we don't have a bike rack. He parked in the Park & Ride and rode it to her college, then set it up for her. I drove him back to the P&R and we raced each other home (sort of!) We didn't stay for too long as DD was keen to get to meet people so once we'd been to the new parents' tea at the Master's Lodge, we legged it.
Exciting times - welcome to all newbies. I keep saying I'm going, but am lurking! Today, I discovered that a couple of my y13s are likely to be taught by DD - how random is that?!
