Though hop and pops are a good way of getting the 'numbers' up.
Doing actual full altitude skydives, getting coached in various disciplines, will also give you the freefall skills and all round body awareness/skills needed when you go towards terminal jumps, and/or onepiece tracking and/or wingsuit later on. If you're already skydiving, might as well actually learn something.
Even when doing hop and pops, don't do it all 'with advice from the internet' but get some actual coaching on flying, landing etc. as there is a lot to learn, and just banging out 'numbers' is not the best way of actually doing so. Having access to people who can actually maximize the learning in the (intended) small amount of jumps you're planning to do before a BASE course, for sure find those with knowledge and experience to help you out.
Going abroad, to somewhere with good weather. Be it one of the bigger USA dropzones, or places like Empuria Brava, Skydive Spain you'll def. get most jumps in, in a shorter amount of time.
