Email etiquette

Lol so this is a dumb question and I’m not quite sure how to word it but here goes. When your emailing someone, let’s say in my case a daycare. I had emailed them asking if I can reserve a spot for my daughter when I go back to work. I know the people at the daycare as that where my son goes. The lady emailed me back saying she would phone me once the daycare opens to come in and fill out appear work and what not. Would it be rude of me to start my reply off with the word Awesome? I was going to reply with

Awesome, thanks for getting back to me so quickly, we look forward to seeing you again.

Take care and have a great summer!

Does that seem like a rude reply or a normal reply.
