I hope you are successful in making air arrangements and know that you will enjoy your visit.

I forgot to advise you yesterday that the web site orbitz.com had BOS to Hilo RT for $588. I do not recall if that included all taxes. Recommend you check and confirm. If you remain interested in that "deal", I suggest you contact Orbitz and ask about stop-over options on their tickets. Remember that such organizations often get inexpensive but very restrictive tickets from the airlines for resale. I also noted that Orbitz was offering almost the same flights ( all via Phoenix not SFO hence your stopover would be in the Phoeniz area) on America West (as was most of the flights on the $588 deal for around $800--- ----go figure.)
