I'm off to Los Angeles and Las Vegas in mid Oct. It's not a flying holiday specifically (at least that's what I've told Mrs PhilD), but I've got a C172 booked for a couple of days from North Las Vegas (VGT).
I took a bit of night instruction here about 2 years ago, but I've never really bothered with completing the rating as there are so few airfields that I fly into which are open after dark anyway, especially in the summer. However in the US it's very different, as I'm sure you know, with pilot controlled lighting and 24hr airports the norm (and no landing fees, and courtesy cars and friendly FBOs, and cheap avgas, and free personal briefings, and flight following, and GPS approaches, and IFR geared up for GA, and no low-level Class A....but that's another story).
I can restrict myself to flying during daylight if necessary, it's not a big deal, but I thought that it would be good not to have to rush back to VGT by SS+30 if we found somewhere interesting to go.
I think I'll plan to complete the night training asap and then see if the CAA can get the rating issued, or at least get my logbook back to me. Fortunately I'm not very far from Gatwick, so I can take it in personally if I need to.
BTW - a related question, all 2h30m of my night instruction so far was done 2 years ago. I can't find any restriction in LASORS on how long the training can take, so I am assuming that I can just do another 2h30m now to complete the 5 hours, not have to start again - any views on this?
