7 nights in July: Endless Summer Dockside for $750 or Sapphire Falls for $1100?

I've already booked 7 nights in Portofino, so we're getting express passes for 8 days. After that we're switching to cheaper hotel. It's our first time in Universal Orlando, from the reviews and the photos I like Sapphire Falls more than the Dockside, but is it worth $350 more? I am 70-30 right now for SF.
