I wish I saw your post prior. It depends on your budget. If it were me, I would not stay there in Fort Pierce and that is my professional opinion from my job. I would go a little further South,Port Saint Lucie and try Holiday Inn. It is only $20-30 more on the some of the booking sites but will be in a better area and quality of room,alone or not. There are also some hotels in Vero, which is not far from Ft. Pierce and I would rather stay up there or in P.S.L. personally. If you can cancel, I would do so, seriously.
