Hi,
When I moved to ATL back in 2011, I had to spend 3 months in temporary housing. I compared the options of corporate housing vs a RI.
Yes, it's only 5 pts per $1, but for less money than a corporate rate, I was able to get a 2 bedroom suite with fireplace. The RI had a standard 30+ night rate, and when I called them, I was able to get a few extra dollars off. In addition, after 30 days, I stopped paying sales tax on the rate.
So, in my case, it was cheaper than Execustay or other corporate housing and it came with daily housekeeping. Plus, I accumulated 90 nights towards LTP (plus rollover).
And for rate deals, check what they already advertise, and then give them a call, or if you have multiple RIs in the area, try to call a number of them to compare.
Cheers,
GenevaFlyer
