Our very first trip was 8 days. We didn’t have Hopper and saw no need, since every park was brand new to us, we needed multiple full days at each park to see and do all the things
Second trip was just me and DH - just 3 park days — we had Hoppers and used them once.
Our next trip (originally planned for Spring Break 2020, after several reschedules is current for Spring Break 2021) we’ll have Hoppers as part of military promo tickets and are staying at Crescent lake. Our pre-COVID plan was to hop into Epcot for festival food after days at other parks. We’ll see if that’s reasonable in April (limited park hours make hopping less do-able).
