For me: no matter how much you clean your house, it never looks as neat as the hotel room, no unlimited towels that 'replace themselves' every afternoon, no room service delivered at 3am, no sleeping until noon.

You?

Jet lag.

Overall being home again, back to reality after having a great time!

Coming home to a messy house. I don't cleanup beforehand, and usually on the day that I'm supposed to leave I'm so frantic to get packed and that I haven't forgotten anything, that I leave my place in shambles…drawers pulled out, clothes on bed, papers on the dining room table. THAT sort of thing. Having to cope with your vacation ending and coming home to that is just the pits.

I think it is getting back into the routine of things, and missing that feeling of anticipation I had before I left.

I've never been on a vacation but I think for me the worst part would be coming back to normal life again and having all that day to day routine and responsibility.

That four letter word. W-o-r-k.

I pretty much echo everyone else's sentiments.
