Feeling Guilty Charging NF after Travel (Aspen, CO)

I traveled with a family this weekend and i’m feeling guilty after charging them - is this normal? I don’t know why I feel so guilty!! I sit for them regularly and feel very comfortable with them and their baby - we also talked about pricing beforehand but it’s just so much added up!

Here’s what I charged

I drove myself 3.5 hours each way + 400 miles = 0.70¢ per mile

and I spent 11 solo hours with the baby so I charged my regular $30 rate

(18 hours total at $30/hr rate)

and $120 overnight fee for two nights

total of $1,060

maybe I feel guilty because this is so much money to me but maybe not to them?? I’d love input/feedback/is my pricing fair??
