I would also suggest, in this case, that you base your choice of "somewhere nice" on factors other than using your points. Consider them a nice bonus if there turns out to be a hote that is convenient for your trip and is part of the chain.
As an example, I've used my IHG points to cover two nights in hotels next to the airport when I have had stupidly early flights. Other than that, I have always been able to find a decent room outside of the major chains, often for a price that is well worth paying just to avoid another hour or two of daily transit time and taxi costs.
This last bit applies more often, I think, outside the US.
