Tipping Mousekeeping in a Deluxe room (Junior Suite)!?

[Along4theRide]

I've been trying to get everything ready for our 1st trip. I just got done printing off some Mousekeeping envelopes and wanted to prepare them, but I can't decide on how much to leave. It's going to be 5 (3 adults and 2 kids) of us in a deluxe room (Junior Suite) at WL. At first I thought $5 was enough, given the $1/person "rule", but seeing that it's a bigger room I think we should leave more, but I'm not sure. What do you think!?
