This title is available from Amazon, for a price! Starting at $34.99, for supposedly a used VHS copy! I suspect it might be out on DVD within a year or less, for less money.
Over at Bygone Video, it seems to be available for $16.95 plus shipping
Quite a bit of time has transpired since I posted the above information. If you've read through this thread, you can see Without Reservations is available as part of a boxed set, and also on its own in DVD, from Amazon, for $11.49.
