As far as value is concerned in relation to what's paid, I think it's roughly equal.
WDW for my family of 6 is setting me back roughly 5,000 (not including airfare).
That hurts, but I'm totally comfortably with that.
Even staying off property I couldn't get that number to drop much (I'd have to rent a mini van, get a suite somewhere, pay for gas, probably have to deal with resort fees, parking, drive in an alien city), or at least to where it'd make a dent. Yeah, I know, peak time, yada yada. I wasn't expecting different.
My 5 grand get's my brood picked up from the airport, transport around the property, board in a fun hotel (I almost went with All Star Music, but I let the kids have final say. Nemo won out), no worries about parking, getting lost, admission to pretty much everything on property (got water park &more + park hopper and the much derided QSDDP). And the assurance of something not getting messed through Expedia. :/
Did I spend more than I probably should have? Yep. I'm aware of that, and accept that.
I didn't really take Universal into consideration when I was making my summer plans. I actually assumed it would be more (growing up in SoCal my dad always said Universe was more expensive, my bad for not doing research).
Ultimately what it came to was me wanting to give my kids a little bit of what I had growing up, and then some. As I've said, never been to WDW. It's an experience, and we're going to have ultra-fun. That's really what matters.
From what I can tell for the same number of days at Uni I'd spend roughly half (staying at Cabana Bay). As far as I can tell, no dining plan, so what- add a couple hundred for food? It looks like there's shuttle transport to the hotel from airport, so that's cool. The two parks are walking distance right? So no worries there
But... is there enough content to fill 4 days? I guess? I just don't know. It's on my list, but not for the first major theme park excursion.
Maybe second. Maybe if I can get the money together for a October trip. That'd be pretty fun.
