Twilight Bag Drop

We are off to the Caribbean from LGW in a couple of weeks and have upgraded from our usual PE to upper class for the first time
We normally check in online and stay at Gatwick the preceding night to avoid the M25 at 8am, dropping the cases into the twilight bag drop when we arrive.
Question is what will we miss by not using the UC check in ..... apart from the obvious which does not bother me ..

You won't miss anything.

You won't miss anything as, unlike at Heathrow, there is no separate UC wing with its own private security channel.

You'll still be given access to fast track security for the next morning, and you'll still get to use the Clubhouse as normal.

Good - thanks. Next the quest for that elusive seq1.
