Hi Ben,
I think I'm right in saying that the Ryersons cabins were B57, B59, and B63.Arthur and Emily had there own of course and I think Jack shared with Emily Borie (unless they shared with there parents(???), Jacks Governess, Grace Bowen shared with Suzette and I think Victorine had her own cabin so it probably was B61 but I'm not to sure.
and Ben I think the Allisons were millionaires to, Charlotte Cardeza also was a millionaress as was Helene Baxter,I think Ida Hippach might have been to,hope this helps Ben.
