Trixie, I was the same the first time I went alone without hubby and kids, but was fine once I checked in,
I don't know how old your kids are but mine were in late teens when I went 4 years ago, my husband had the place shipshape while I was away, no cooking 4 different meals every night, and running them here there and everywhere, etc. I arrived back home to a perfectly tidy home, and we'd all missed each other, so lots of hugs etc. Life was beautiful, until a few days later when they remembered I was back

then things got quickley back to normal.
Wouldn't have it any other way though,

you enjoy yourselves

and like jivebunnie said, we can stroll round safely there, couldn't agree more.
