Take a bottle of water and a couple of cereal bars. I found this kept the blood sugar up and concentration high.
Agree with Fuji about talking to ATC and the ground staff. One of my stops was Bournemouth and they couldn’t have been nicer and made the final leg a real confidence booster. I didn’t do anything new though. I think you should just follow your plog and fly as you’ve been taught.
The feeling of satisfaction is up there with first solo and skills test pass.
Good luck & enjoy.
