The first time we went we were on honeymoon and we stopped off one night in SF out and LA back
And it was terrible to get out of airport go to hotel sleep go back to airport and check in again
Also on the way home we had a crate of pinapples we were bringing home for family etc from Hawaii and so we had to take them to hotel for night
This was 15 years ago, wouldn't be allowed to do that now -- these had been checked by enviromental dept etc for export and inport etc. We were not allowed to break seal and eat one although they smelt wonderful
Deffo better to spend the time in Hawaii and connect the flights with a couple of hours to walk around aiport
or do SF or LA properly and spend few days there
