I don't have the Adventure Awaits add-on, but the icon for the trip appears when I'm organizing a personalized wedding. Time doesn't count down, so I can't end the wedding. I have to save and exit to...
Ideas
I just encountered a bug where my Sim's wedding (with My Wedding Stories) can't end. There isn't an X button to end it like normal (pictured below) and the wedding event no longer appears on the calendar.
The only solution I've found is to exit to the main menu, click "load game" so you enter the save via Manage Worlds rather than live mode, and then visiting a different lot with all of my household's Sims.
I have most DLC installed except a bunch of kits, Life & Death, Enchanted by Nature, and Adventure Awaits. I also play with script mods (including a few UI mods) and custom content installed, so I'm not sure if this is a mod bug or a game bug. That said, none of the script mods I'm using are new to me and I've never encountered this before with them installed.
I just had this happen. I was able to go into cas, then click manage worlds from there. Went to a neighbors place and invited my sims there and was able to get out of the event. I know it’s a little late to help you but just in case somebody else is having the same problem.
