Yeah, that's why I've started liking the idea of long rests are a week of rest, with short rests being a single night.
Really makes the resources a lot more precious if you're not getting them back during the same session. So many times of players being like, "whelp, I just burnt five spells, let's long rest"
What I should be doing is if you're long resting in the dungeon is having monsters show up, but I can literally see my players eyes glaze over when it's a random encounter like that.
