I'm with the OP. I believe the OP should be getting whatever Destination Fee "perks" are supposedly provided for rip-off fees (that they luckily don't have to pay).
When booking a room for 14+ days at that hotel all the rate code says is "Destination Fee Exempt" and it tells you what qualifies for that rate (14+ nights). It does NOT say "Destination Fee perks not included".
I understand the argument "you get what you pay for". Or, in this case, you don't get the perks because you don't pay for them. However, I believe the spirit of the lower fare is "hey, you're coming to stay with us for a very long time. We'll waive the fees." This is akin to "stay longer" rates where the rate is 15-20% lower than normal. You don't get 15-20% less room, do you?
