Tpa/mco/sfb
Have been Florida a few times & have friends who are expats there. When I said next time I may route through TPA they looked at me like I was mad. I'd say avoid Sanford, have heard little in the way of compliments about flying through there, be it facilities,location,access. MCO is a short hop into Orlando, just remember to bring plenty of quarters for the Toll Roads. Immigration whether arriving on a domestic connection or direct from UK wasn't a problem - on one occasion they even allowed wifey to re-do her waiver form again while they 'processed' me & junior. You'll probably find more value & choice with a direct UK-MCO flight rather than to TPA but if you route through a US hub then it really is swings & roundabouts. TPA is about an hour's drive from Orlando (Downtown even more) & that's with flowing traffic which may also be a point worth considering. Friends advise getting out of TPA after 4 is a 'mare
Suppose Immigration quality dpends on the day..everyone has bad days. Could be worse you could be flying into New York
Right, I'll get me coat........
