I'm not a veteran DM but I have recently started running a game (just done third sesh) and i'm playing in two other campaigns, one of my DMs would love for someone else to run a oneshot so he can be a player for once. Was wondering if people could recommend a premade one shot adventure, preferably from one of the adventure books available on DnD Beyond as I've just bought the Legendary Bundle ($150 off, why the heck not).

I have run a oneshot before that i created myself but it was kind of a nightmare as I massively overestimated how much i'd be able to fit in and ended up having to rush the whole thing to get to the end of the story in one session, I know I could have stretched it to two sessions but I didn't really feel like what I had was worth that much effort to expand. In my main game I love to world build but it's kind of alot of effort for a one shot, I really wanna just have something I can pick up and run with. Also I've never really looked at the adventure books and thought this would be a great opportunity to dip my toe in.

Any thoughts would be very welcome.

The Saltmarsh and the Yawning Portal books are both standalone adventures.
