Having been a similar situation I ended up using the tray soak method. Put the prints in the tray & let them soak for a half hour. Then dump & change the water a number of times. Per residual hypo testing 7 changes of water over a 4-5 hour time period with 6 prints in an 8x10 tray came out clean.
I would run at least two changes of water before going to bed at night & then the rest in the morning inbetween breakfast and skiing around town to check on stuff.
David Vestal in an article I think was titled "mysteries of the Vortex" printed his results of soak rinsing in Photo Techniques a few years ago. It is worth getting for the information.
