Kanu,
I'm not saying don't go to the IOW. But it's a long way from Manchester for a new PPL, and IMHO too much of a challenge for a first flight. If you have someone with you with a lot more experience, it's perhaps a different matter. But in any case, it will probably be further than you've ever flown before, and involve a water crossing, and involve dealing with weather unless you're very lucky...how often do we get good weather over the whole country for that long? And as I've said before on this forum, I think that ONE challenge at a time is enough in the beginning!
Many people are too cautious after getting their PPL, and won't leave the local area. But I suspect an equal number are over-confident. Why go to the IOW now? What's the rush? Do something more local first. Do something you feel reasonably happy with, that's maybe just a little more than you've done before as a solo student.
My first post PPL trip was Welshpool to Caernarfon, because I'd always wanted to do it. I managed to fly over the mountains to get there (PPLs who learn at Welshpool cut their teeth on mountain flying), but then the cloud increased and I had a long trek round the coast to get back. So even that was quite challenging.
If you take someone along, be careful who it is. I'd never flown into a large airport, and on a very early flight went to Cardiff with someone who I though was much more qualified. He flew down, and when he started flying us round a beacon in circles, I realised he was...confused. He had 185 hours, which sounded like a lot to me at the time. It isn't!
If you're in the Manchester area...
Caernarfon is a nice first destination. Or if you're thinking about the IOW, why not try somewhere part way - Shobdon, Wellesbourne, or Gloucester - then part of the trip will be familiar when you go further afield. Or if you learned at a small GA field, fly in somewhere big with full ATC, or vice versa. You have all summer for the long trips, so make haste slowly.
