My family of 4 is going to Disney in feb. kids 6 & 2.5. Right now my husband myself and I all have fp for FOP but my youngest doesn’t need a fp plus he doesn’t make the height requirement. My question is if I change my fp to something else to ride with him while my husband and oldest go on fop will I still be able to do rider swap? Or would I need to keep my fp as well. Thanks!!!
