Wondering what to expect on using the ART shuttle? We have only stayed walking distance before but have lots of Hilton points so looking at staying at one of their properties, probably in garden grove since they have more availability. Is it really bad at the end of the night waiting? Or long wait times to pick up due to over crowding on the bus? Should we just drive the rental and park?? We are not used to public transportation as we live in a more rural area, but are familiar with the Disney world buses. Is it similar to that?? Thanks so much!!
