Last night (and again today) I checked on the whole range of dates (from today through 1/31) to double check the rates that I have booked have not declined. At first pass the rate returns $25 lower for the entire range but then after I cancelled the existing reservations I tried to rebook the individual dates and they all return to the rates that I have booked. It also returns to the higher rate when I search on the entire date range again. GRRRRRRR. Same thing again this morning (I knew better than to cancel the existing reservations this time).
