Hi Emilia,
Welcome back to the Disney Parks Moms Panel! I'm so happy you are planning early and doing your research. I can already tell your friend and daughters will have a magical 1st trip.
Night of Joy is a wonderful event. Just today, the 2015 dates and artist line-up was announced and it sounds like it is going to be an amazing show! In case you missed it, check out
this great post from Disney Parks Blog.
I did some digging and found some pricing information from
2014. Last year, single-day tickets were $59 plus tax with advance purchase and $69 plus tax on the days of the show. A special 2-night ticket option was also sold for $108 with advance purchase.
Tickets for 2015 should go on sale in Spring. To get the latest news and information, please continue visiting the
Disney Parks Blog or the Night of Joy Facebook page. Of course, we are always here to help out too.
I hope this information is useful to you and helps you in your planning and budgeting. If I can be of any further assistance, please let me know.
Happy planning!
