Hi - semi urgent question. I have had to move a positioning flight today from LGW to LHR. Leaving T5 today, arriving back T3. If I book either the T5 long stay or T2&3 business car parks - it is still fairly straightforward to walk between them? I have used T5 long stay a few times, I assume I just park near the exit (between D and E I think) - will I be able to just walk in/out through the barriers as below?
Thanks
