Now, we won't even consider staying offsite. By the time you add up the rental car, paying the parking fees each day, gas getting to and from your offsite hotel to Disney property, it costs about the same as staying in either a value or moderate resort onsite.
Wow. I really disagree with this. Like I posted on another thread....next spring, our trip in a beautiful, Disney themed 3 bedroom condo, with a pool on par with the deluxes, will save us $1354 over 2 rooms at a value resort. More than that if we were in one room again at POR. Parking is only going to cost us $88. We already have our car, but I doubt renting a car and gas is going to cost $1100 some.
OP...........we all have our opinions. One thing I have found out for myself is that EACH FAMILY needs to find out for themselves.
I used to be one that would ONLY stay onsite. That is, until I had the dreaded family of 5, meaning, hotels are catered to families of 4. You either have to cram yourself into one mod room at POR (which we have done and survived), pay for the more expensive deluxe room, or pay for two rooms at value (or family suites which are about the same).
Sooooooooooooo.........we tried staying offsite in 2 bedrooms condos. Does it have that magical feeling you get when you stay on property in one of the monorail resorts? Or Epcot resorts? Probably not. But for us, it is more magical than a value room (don't ever want to do that again if I can help it) or a room at the mods.
For my family, and this is MY family..........I will tell you what is more magical. Having MY OWN master bedroom with king sized bed and bathroom with jacuzzi

, having more than one tv so I don't have to watch kids tv whenever we are just chillin' in the room, having a big fridge so we have all the ice we want, cold drinks, breakfast stuff, having a washer/dryer so I can just throw our laundry in before we go to the parks and I don't come home with tons of laundry (that was always a real bummer), AND last but not least........after a long day at the parks, being able to park right outside my condo so I don't have to walk a mile to get to my door!! Ughhhh! I loved the POR landscaping, but hated those long walks to either the bus or our van.

It was the same when we were at AsMo. And the only perk I miss is the bus to MK also. Everything I don't use or don't need.
You never know until you try it. If it was just DH and me, I would be onsite. I would miss the kitchen, but I could do it. I would have never thought I would be one to like offsite.
Also wanted to add..........if I'm going to stay offsite for whatever reason, I wouldn't just get a plain jane hotel room. that has no magic in it for me. What we have stayed in were more luxurious than that. Every family has to do what they gotta do........some can only afford those hotel rooms. And that's ok.
There's no right or wrong answer. You have to find out for yourself.
