To get them to finally leave us alone I told them I thought the condos were a bit dated and ugly.
This is really the best strategy. They can argue all day with you about price and convince you that you CAN somehow afford it. They cannot argue with someone who does not like the resort. What could they say..."Yes, you do like it!!" I usually tell them it looks too much like a typical college apartment building (which is true) and not like a Disney resort.
We've done a few in our lifetime--they are annoying and take forever but you go usually get a cheap stay or free ticket. Good luck!
