I'm not going this year, unfortunately, but will go in 2016. I usually don't do daytime Universal when I do go but in 2016 I'm going to combine both and stay onsite. Really looking forward to planning that trip! I will buy the ticket for more than one night and go maybe 4 or 5 nights! It will be crazy!
i do that for hhn every year.
stay onsite and go in the day and stay for hhn.
you will love staying onsite and hitting everything during your stay.
make it a marathon time and do the parks around noontime, stay when the parks close in the holding area and begin hhn before the park officially opens.
great thing is you are on site and can easily use the water taxi or walk back to your hotel room.
the hhn pass for admission (and some include the express pass) is money well spent when you go multiple nights.
i hit 6 nights last year for it.
have fun planning for 2016!
