For any of you whom have already booked a room only prior to a promo coming out, how easy is it to just call and ask for the promo? Do you have to cancel the original and then rebook; or will they just change to original to reflect the promo?? Also we are booked for 8 days now....if we cannot stay for 14 days will I just pay for 5 and get the 3 free? TIA
