Talked to the manager at the Palm Harbour Marina this weekend, and he said there was no problem with leaving you car and trailer for a few days. It would be better to do it during the week, as this place gets real busy during the weekends, and parking is limited. If you did it over a weekend, they may charge you a small daily fee ($5-10)for storing you car and trailer.The marina is fairly secure at all times. We have had our boat there for 3 years, and have not had or heard of any vandalism problems.The only other consideration is the tides. If you have a winged keel, like ours, you can not get out at low tide. You have to come and go out after the tide is at the 1 foot level. Swing keel should not be a problem.Have any questions, let me know.Thanks,Sam
