Thanks Ladies!
I think I will look into one of the plug-in sterilizers...just for her piece of mind...(she might change it by then and be ok with the hot water and soap, but you know - hormones after a newborn...you just want it right!)
and we have thoroughly checked out the rooms (my aunt booked it for us...) they have 3 other kids in addition to the baby, and I think their room adjoins to my parents...but we all have 'bigger' sized rooms to fit everything! (our room will have 2 pnp in it - or we can use the pull-out couch...so it must be pretty good sized!
we are getting very excited! there will by my parents - my 3 siblings and spouses - and the 7 grandchildren!
