D'oh !!
Um... (thinks for a minute) well, duh, obviously I meant invite them in the winter when it's bitterly cold in both places and Florida doesn't seem so far away. Yeah, that's what I meant !!
It's not too bad, really, although it is kind of mind-numbing (although not as bad as archaeology). You can download a series of test tones from RealTraps and burn them onto a CD so that hitting "next" moves to the next frequency. Then you just set up the SPL meter on a tripod in a reasonably readable position, step through the frequencies on the CD, and record the SPL meter reading at each step being careful to stand in exactly the same place every time so as not to muck up the readings. It's easier if you have a "reader" and a "writer-downer".
Here are the instructions from the Rives CD :

You push a key, it makes some wierd noises, digests the results for a minute, then spews out not only frequency response charts but spectral decay graphs for all the frequencies, eg "the room is too absorbent at most frequencies but has an evil echo at 500 Hz".
