I believe you have a Majesty Palm. I find these palms make a bad transition to the indoors. Even though you may have purchased indoors at the store, most likely most of it's life has been spent outside or in a greenhouse and was even acclimating while in the store. If you plant to keep your plant indoors, aday or two outside then back inside surely won't hurt the transition. And misting. Palms LOVE to be misted. In fact they LOVE humidity.
