I think the likes of BCFT are trying to play to the requirements of airlines like Flybe who specify that if you go modular, all the training must be done at one school (apart from PPL).
The structure they are offering is no different to what you could come up with on your own with an Excel spreadsheet, but it is nice to have a timeline fairly well in place with the school, as it keeps you on track and stops the spending running away with you with extra hours or groundschool here or there.
lots of schools offer "structured hourbuilding" however, you may well find there is no structure at all. Ultimately it's up to you to make the most of the hour building phase. BCFT have plenty of aircraft available for this, so long trips away certainly shouldn't be a problem.
