Lightning Lane Forum

On the video about Genie plus that was posted 6 days ago… It mentioned that getting a lightning lane for a party of four would be easier than for a party of five. We are a family of 5… me, my husband, my 8 year old, 5 year old, and 2 year old. My question is…if I know my toddler or even short 5 year old may not be tall enough to ride certain rides (we plan to use “child swap” which I assume is still a thing), should I book the lightening lane for only the family members eligible to ride it and scramble trying to remember who is tall enough to ride what or do I just book lightening lane for everyone ? Thanks for any tips! I haven’t been to Disney world since I was a kid and first time going as a parent!
