As for the stay 4, pay 3. In my experience, not nearly as good this year. I requested pricing for an upcoming stay. Received 3 different quotes varying in price by $600. 24 hrs later requested to book the cheapest price, only to get a 4th price which was more expensive again. Explained that prices constantly fluctuate, etc. Considering the stock email from citi now says that all requests will be responded to within 24hrs, i don't know how you can get an accurate quote by their reasoning?
I don't understand big_head. When you say you got three different quotes which varied by $600, was this all in the one email from them, or over several different quote requests across different days? Were the quotes all for the same room type?
I have had great success over the past few weeks with this benefit. I usually email Concierge the hotel name, number of ppl and room types I want quoted, and I get a comprehensive email back within a day outlining the options. In all cases they've been much cheaper than I could book anywhere else online. The price fluctuations occur in my experience due to currency changes. There have been a couple of times when the price did change by more than just currency fluctuation, but I also noted the price on hotels.com changed too - any hotel or airline booking system can have price changes willy nilly so I accept that's just the price you pay if you don't lock in the quote asap.
It is ridiculous that Citibank seems unable to get a quote straight away in real time. Or allow us to claim these sort of things online. I have also found booking the free night to be very complicated since the concierge seems to have to send the hotel an email to check availability, then check back with me if it is OK (where I have previously indicated that I wanted the free night at the hotel he/she is checking!). Not to mention the very poor range of choices for the single free night.
This also hasn't been my experience gregff. I've been on the phone with concierge for about half a dozen different bookings over the last month, and each time they've provided me with instant quotes on request. That's not just for already quoted hotels from emails; it's for new hotels, dates etc. I get the quote, decide if it's the best price, and book accordingly.
I've found the deal to be awesome, and over these recent bookings have already saved >$2k. I'm currently living in Canada, so concierge will even call me back on my overseas number to make the booking!
