We're planning to visit YNP the first week of June and have gathered lots of information from this great forum. The park sounds and looks breathtaking. Of course, we're really wondering about the weather at that time and what to pack to be prepared. Will the weather be more moderate by then? Also, will there be mosquitoes, black flies, or any other insects of concern at that time? Do the park hotels have hair dryers in the guest rooms? Thanks for any help.
