There is no fix. The suggestion was to go back to the last saved game before the issue was presented and installing the latest AwesomeMod, which I already did. But this did not fix the issue.
I have a backup of my game before traveling and I still use it to test many differents way to come back from traveling and avoid the sim jumping out of bed but nothing sims to work. I continue to play (keeping always the good backup copy) but I cannot send them to travel because they come back with the same bug.

I never claimed to be special. But thanks for it.
After reading this thread, I see the solution was not found. I see a suggestion but not a fix.
On July 6, 2011 this was posted:
"We're aware of what causes the problem already. Unfortunately, you will have to revert to your pre-return-from-vacation save to ensure a clean sweep of the problem. Grab the latest AwesomeMod"
However, after installing the latest AwesomeMod, the problem still exists.

Annan, somehow I'm feeling special after knowing I respect others after they insult me.

Annan. Why are you so bitter? I said thanks to your response before.
Anyway if anyone finds a solutions please let me know.
Thanks.

Hi all. I see this topic is old but I was directed here about my game issue.
My sim also cannot stay in bed for longer than 20 minutes (sims time). It happens only after I send my sim to travel.  I have a copy of my game (thank God) before the travel, and I keep using it to test what could fix this but nothing works. I deleted all mods and tried batches at a time to find what is causing the glitch, but found nothing. I also played without custom content and nothing.
Did any of you found a solution to this?
Thanks.

Thanks. I saw that one before but didn't post there because it was too old and seems no one found a fix. I will wait until someone repairs this glitch.
Thanks again.

Hi. I am new here. I hope I'm leaving this post in the right place.
Okay. My sims played normal until I sent one of them to France. She came back and the first problem I noticed was that she would not stay on the phone with anyone for more than 20 minutes (sims time). Then I notice she won't stay in bed. She immediately jumps out of bed. She can only nap. I have tried almost everything I can possible think. I even uninstall all of the sims, including all expansions, but I still get the same problem.
If this is not the correct place for this post please at least direct me.
Thanks
