The ATCOs in Jersey & Guernsey are very helpful & friendly.
The only time you may have a problem in Jersey is when they are busy they don't allow circuit traffic.
Class A CICTR is never a problem for a VFR pilot, just do as they tell you & you're fine.
Thousands of visiting GA pilots from all around Europe, over the years will testify to this.
Give them a try.
Any questions for travelling to Jersey will be found on the Jersey Aero Club Web site:
www.jerseyaeroclub.com
At £3 per 1/2 tonne charge with 168 hours free parking on Jersey (handled by the aeroclub up to 3 tonnes) you can't really afford to miss trying the CICTR 'Class A' airspace.
Enjoy a Channel Island trip.
