It would be the week starting June 28th and there would be 5 of us. Do any on site rooms allow 5 people without the cost of a suite? Youngest is 16 years.
You want to visit for 2 days. Taking it down to a barebones stay, that's just one night needed. Get to the hotel early on checkin day, do the checkin process and get the included Express Passes, then head on over. You get those unlimited EPs for BOTH days, and early entrance to Wizarding World for both days as well, with just that one night.
***note: I'm talking about the 3 deluxe resorts here, Royal Pacific, Hard Rock, and Portofino...Cabana Bay won't have the EP option and who knows how they will do everything else...***
I use
this site to book a room-only reservation with the Universal hotels.
Using 4 adults and 1 child (making assumptions based on what you said) you could go through that week one day at a time and find the deluxe resort (NOT Cabana Bay!) that's most budget for you.
I would bet quite a bit of money that one night would be LESS than buying 5 Express Passes, especially realizing that you would want EPs for
both days you want to be at the parks! And those are limited, not unlimited like what is included at the resorts.
Question! Where are you staying in Daytona? I've just decided to stay at a hotel while visiting family out there, and I'm looking at resorts. (for January, so the pools aren't as big of a draw as they would be in June)
