Neither the Hilton or the Sheraton are honestly all that nice. The Hilton is the nicer of the two but still doesn't feel Disney resort nice (even Paradise Pier!). It's very "business," I guess the rooms could accommodate five people, but it would be pretty tight in one of their 2 queen rooms.And Universal's room can accomodate 5 people.
Even with that, some nights are pretty good at ~$200 rates but a lot of nights you'll be up in the $300s, especially after tax. Still way cheaper than Disney, but you could easily spend $1000 staying three nights over near Universal. (I'm spending over $400 a night two different nights the first week in October, likely because of Halloween Horror Nights, though to be honest I also booked a Universal view room. They've got great views of the park!)
