You can always try to contact the hotel directly and ask for a better deal. The hotel splits the Groupon cost 50/50... So the $280 for 3 nights only nets the hotel $140. I stayed at the Treehouse last year (9 nights worked out to $600 with Groupons) and contacted them earlier this year when they had another Groupon, asking if they could beat the deal if I paid cash on arrival. They did, but it didn't fit my travel plans at the time. Should have jumped on it though, because we managed to squeeze another trip in next month.
