I have a 15yr old and a pre teen (almost 12) and a 2yr old and to be honest, if they want to sleep in, they'd better get used to the noise. I am a noisy person by nature anyway so I guess my kids are used to noise now.
I think your plan for letting your DSD know what time you will be starting your mornings is a great idea, that way if there is noise, she should already expect it.
