My mother has a very difficult time lifting her legs to get into vehicles due to her daily chemotherapy medication. Makes her very weak at times. My dad put running boards on their mini van to help her. Right now, we have DCL transportation booked for our October Cruise, but am thinking of changing and getting Happy Limo booked instead because I am worried that my mom will have difficulty getting onto the bus and I want to save her embarrassment. Does DCL have lifts for handicapped people or should I definitely get happy limo?
