Well, yes, there is some public transport around Torres de Aloha and the bus stops are directly in front of the main gate on Avenida del Prado at this map location.
The busses are number 4 & 5 going to Puerto Banus and San Pedro. # 4 only Sundays & Bank Holidays, # 5 Mon-Sat. You may find walking there and back as quick as using the bus. Rented bikes will be the quickest & easiest to park option.
