I've flown into Weston many times and while you need to make sure that you're not encroaching on the many restricted areas around there, it's a really great airport to fly into.
Lots of cool aircraft in the hangars to leer at and the cafe upstairs has some decent food with a long bay window looking out over the runway.
The most important thing to watch for in Weston is making sure you don't encroach on the Baldonnel MOA's and RA's. There are a lot around there and subsequently circuit procedures are modified in Weston to avoid this.
Just be clear on your entry and exit procedures and you'll be fine!
Other than that, here's a few pointers:
1) Fill in the GAR form
2) Fly high enough that if the big fan stops, you're glide will take you to land
3) Measure your halfway point, so that if you encounter any issues like having to go to the loo
or any other reason, you know which direction is the shorter trip.
4) Bring along either an immersion suit or some life jackets.
5) Enjoy!!
