Benefits: Lunch somewhere nice first and/or dinner after. If going to London, home before the trains get slow/unpleasant/noisy, if locally, find y our way in and out of car park easily and home in daylight - at least from now on)
Disadvantages? can't think of any!
OK there are more older people perhaps, sometimes families (such as when we saw Kiss Me Kate in January, but all ages/shapes and sizes.
Sunday afternoon cinema as well- a great treat, DD and SIL (no kids yet) love it! What's not to like?
