I need help with a quick question. I have been stuck with the burden off booking 2 rooms for my LOVELY (NOT) sister who is working. I have this week off from work and I'm doing the favor for her. Is a credit card required when u call CRO to reserve a room. The trip is for july and I think there is still plenty off time for her to get a room. She didnt leave me her CC number,and I cant call her at work cause she is never in her office. So I was wondering if anyone can get back to me and let me know so I can get her off my back and start enjoying my week OFF. Thank you for those that help.
