recent trip... poly lvc around $700/night...
funny that dh and i were just discussing this topic... when i recently talked him into a summer wdw trip (HAVE to use those ap's!), he said he couldn't believe how much money i'm willing to spend on vacations, especially disney ones...
i had to point out that we don't really spend money on other recreations during the year... so many family/friends spend money every week on things i just wouldn't... beer, smoking, expensive food, excessive clothes, etc, etc... we're not spending like that during the year, so i can justify it (in my sick little disney mind

Everyone has different priorities.
what it comes down to is if we didn't have it, i wouldn't spend it. we pay cash for our trips, we save more of our income than anyone i personally know, our kids have college funds and IRA's... of course i'm going to stay in a nice hotel in disney! i would be crazy not to. BUT if i couldn't afford it, i'd do moderate, value, camping, off-site, or not go at all, and that would be fine with me if that was the boat i was in (which was my boat basically my whole life until fairly recently).
OH, and we honestly enjoy the resorts as much as the parks... i think that makes a huge difference as to what someone is willing to pay. i actually put more thought into the planning for the resorts than the parks. for our upcoming trip, i know it will be HOT, so i'm planning on hardly doing the parks and enjoying the pools. so i'll gladly pay for whatever strikes our fancy. AND location, location, location... nothing as magical as watching the castle change colors all night, seeing the monorail glide by, watching the boats on the lake, seeing the other resorts all lit up... i gladly pay for that because to us, our room is soooo much more than just a clean bed and shower.
one more OH... i was pricing a summer trip to New England instead of disney - at least $450/night for a resort on the beach - a crappy pool, no slide, and nothing else to do... also jersey shore (long beach island specifically)... at least $6000 for a week for a house on the beach (not one of those awesome mcmansion houses either, no pool - the mcmansion houses were $9500 for one week)... i'd rather go to disney, stay in an awesome, awesome resort and have all the recreation, magic and safety disney offers at my fingertips.
