I'm always a fan of flying slightly more intensively than the '2 hours at the weekend' style of training. You have less catch-up and refresh time that's essentially just wasted hours, so having several days off in a row to get as much done as possible is probably a good idea.
However, I'd say you'd be lucky if the weather doesn't interfere with those plans!
If you're aiming for minimum hours, you have to plan your remaining time well with respect to the weather, otherwise you could be waiting for QXC or test for weeks with no hours in the bag to practice before hand. Obviously in this situation you simply put your hand in your pocket and pay for more.
Start your ATPL groundschool as soon as you like after the PPL. Build hours at the same time, so in the circa-9months it takes you to do the ATPLs, you'll have the P1 time required to start CPL training.
