I am in a certain city quite often for work, about once a month. It took me some shopping around before I found a hotel (with rewards of course) that I like. I tried the BW but settled in with the Radisson. I got to know the head of reservations via email and she has always been very helpful. (I am also Club Carlson gold, which I got for free from a status match from A Club). Not only does she always give me an upgrade, but she recently has given me fruit baskets and on my last visit a bottle of wine in a very nice suite. Why am I telling you all this? Because if you find yourself in a similar situation, traveling for work to the same place(s), find a hotel you like, stick with it, get to know the management and reap the rewards!
