Never stayed at Caribe Royale but drive by it each time we go to Disney -
As someone else said, there is a Ponderosa across the street, as well as an Asian Buffet, CVS, 7/11 w/gas station, a Florida souvenier shop an urgent care & a pizza type shop.
The road is four lanes, with a grass median - we see folks crossing the street to the shops frequently. The intersection can back up sometimes of the day. If I need to make a left out of there if I've stopped at CVS on the way to Disney I will make a right hand turn and then a U turn!!
If you go to the intersection (535 & 536) and turn left you are headed toward Rt 192 with all the other touristy Orlando shops, restaurants etc. It's a good location.
