We used LLMP and LLSP 5/12-5/15. We found they weren't really necessary at Animal Kingdom on 5/12 but we also had a day that rained the entire day. I would recommend LLSP for FoP if you're not planning on rope dropping though. We also found LLMP wasn't necessary on 5/13 at Epcot unless you don't want to wait in line for both Frozen and Remy. We grabbed a morning LLMP for Remy and rope dropped Frozen from the International Gateway. We got in line at 8:45 and had a 20 minute wait. It's a good thing we did because by the time we used our first LLMP for Nemo, there were no Frozen LLs left. Again I would recommend LLSP for GoG. The shortest wait-times I saw for that was 45 minutes. In both AK and EP we ended up not even booking LLs later in the day because the wait-times were so low we didn't need them. On the other hand, I would definitely recommend LLMP for HS and MK. On 5/14 at HS we were able to book and use LLs for everything throughout the day. We started with Slinky, ToT and TSM. We rope dropped MMRR, TSM, and RNRC and then was able to get LLs for them later in the day for another ride. We also felt we got our money's worth at MK on 5/15. We rope dropped Space MT, and HM. We used LLs on: HM, Buzz, Tiana, pirates, Pan, IASW and had one for Pooh but it was down during our timeframe and we never made it back there before leaving for dinner. We also used LLSP for 7DMT and Tron. We were four adults so your situation is different but long story short, I recommend for HS and MK. I also found refreshing while standing in line helped a lot to get better times/better selections.
