Hopefully, you have already done it by now. What did you do?
I quite often do the same trip. I usually fly south towards the Goodwood Radial to Liphook & then turn towards IoW. This way I avoid Oakhanger, Solant CTA & Portsdown.
You could also go via Bognor area & along the coast though this can get busy, as can the solent.
As for where to go, I prefer Bembridge, purely because of the pubs/beach cafe's @ Bembridge point.
