Rack rate for a standard view at a value during regular season is $99/night plus tax (11.5%-13%, depending on whether it is POP or an AllStar). I'm not sure where Poohnatic got the $85/night from but no value resort rate rate ends in a "5". So, for 10 nights at ASSp, you're looking at $1118.70 right there.
Disney no longer sell the Park Hopper Passes, they sell Magic Your Way passes instead and they're a little different. Chances are good that your TA quote includes 10-day MYW Premium passes. For 2 adults and 1 child, the Disney advance-sale price would be $843.49 for the passes that expire within 14 days of their first use.
By booking those two features by yourself, the cost would be $1962.19. The difference between the DU quote and booking it yourself may be the cost of
trip insurance?
I don't think that it's a great price but if you do not qualify for any other discount (FL resident, AP Holder or
AAA), then it's probably the best that you can get.
I would not recommend getting an AP unless you can definitely get a room discount. The AP discount for May is $25 off the rack rate but there were not too many rooms made available, so even with an AP, you might not be able to get a discounted room. The new break-even point for buying an AP (vs. buying MYW passes) is 13 park visits.
