Purely from a logical POV, not if you are doing modular full-time. In this case, the benefit of doing an integrated course is that you are doing your training full-time, where you start the next module soon after finishing/passing the previous one. If you are doing modular full-time, then it should be the same. However, if you are spanning your CPL (for example) over a long time (i.e. 1 or 2 hours a week), then yeah, you may find it harder and may need more training, hence costing more.
With the exception of a handful of airlines preferring integrated students, like EasyJet, there really isn't any down-side to doing modular over integrated. Even if you're young and want that 'campus' experience, just do full-time modular all at one school.
