Marriott for Hilton trade?

[VittoriousMax]

It's a bit of a long shot, but I might as well ask.
Is anyone looking or willing to trade a Hilton room for a Marriott room?
I have a King Bed room at the Marriott for Thursday the 26th to Monday the 30th and I'm looking to trade for a Hilton room with the same dates.
I have friends staying at the Hilton and my group has decided that the Hilton better suits our needs.
I've stayed at both and I can tell you first hand the Marriott has a better pool and gym, but aside from that, the hotels are pretty comparable.
If you're interested or have any questions feel free to PM me, email or message me on Facebook.
Thanks!  ;D
