Perfecto,
quiero
hacer
las
dos
cosas.
¿Dónde
me
cambio?
pehr-FEHK-toh, kee-EH-roh ah-SEHR lahs dohs KOH-sahs. DOHN-deh meh KAHM-bee-oh
Perfect, I want to do both. Where do I change?
"Cambiarse" is the reflexive verb for changing clothes. "¿Dónde me cambio?" is the natural way to ask where the changing room is.
