I love those forget me nots Ruby - have bookmarked that page for future reference 
Copt - have a fab time at concert - sounds great (as do the miniature snacks )
Holidaying on chemo - I think again its 'suck it and see' - you'll have a better idea after your first cycle how you feel. I'd say abroad is definitely out (insurance would be v.high) and I'd stick to things that allow you a certain amount of inbuilt rest time, and go somewhere where you can stagger active with less active days (I found that if I was fairly active on one days - I was shattered the next) - but see how you get on, - I'm like copt, low white blood cell count to start with, so pretty wiped out by chemo, and I was on accelerated chemo so having it every two weeks, so only got two or three days of feeling OK before my next cycle. If you are having it 3 weekly you might get a whole good week.
I would say in principle though assuming you feel OK getting away for a few days is a very good idea when you are having chemo - helps you detach from the intense clinicalness of treatment and hospitals.
trice - your niece sound completely adorable - I do love a cuddly wee girl (little boys are nice too of course)
