I understand you wanting to surprise her @GavinCh but as @lrb_03 says, it's best to listen to what she wants. For me, at the beginning, I just wanted to hibernate. I was happy for people to know what was going on, I just didn't want to have to talk about it and I absolutely could not think of anything else. After surgery, (2 surgeries, 2 weeks apart) there was pain from the node removal and there was also the issue of keeping the site dry and clean. Then I had the consult for chemo a couple of weeks after that, and so on. I guess what I'm saying is that until she has a plan, you won't know what is likely to happen, and that plan could change depending on the path report. But ask your wife what she wants and maybe just let her know that you really wanted to surprise her. Maybe the cruise could be kept as a treat for getting through the crap (give a decent amount of time for recovery).
