so are you saying what is done is done are it dosent sound like that bad ??
(of course when the deal is like they say it is )
Can't emphasize enough of what Dan said, but _always_ review the fine print. I don't know what the exact terms of what you were offered or solicited for. Most third party/sponsored offers I've seen for "pay now or you'll lose out" deals will be in lower category hotels and/or come with massive blackout restrictions (for example, the entire months of June-August, holiday weekends, some weekends, etc).
e.g. if i am booking today i can pick a date till 6 months from now . if i am booking on sep 30 i have 6 months fom sept 30 to complete my reservation.
Perhaps these are the sort of questions you should've asked to whomever called you? Again I don't know the terms of the offer, so I would suggest calling them and asking them.
