Maybe a more general question for the TP runs thread, but for multi-leg runs like this where you actually want to stop over for a bit, wouldn't it be more cost effective per TP to structure as a BAH from one of the U.K. regional airports (eg INV?) and just make sure you've got it spread over at least 5 nights with hotels wherever you are that night? At least while the double TPs promotion is still running...

Or is that too much of a logistical challenge (or will the flights not price similarly as a package)?
