Felicia, you're challenging me on my first call with the three-parter. That's impressive. So let me try to tackle it. So let me start with the fourth quarter. Yes, we are seeing a deceleration given our geographic mix, but also in North America. So North America, as we called out was up 9% in RevPAR. We still think North America is strong in the mid-single digit, but we are seeing the group sales being weaker going into the quarter in North America, than what we saw in the first three quarters of the year, which is giving us a pause there. And part of that is, because we did see a shift in the citywides, out of the fourth into the third in markets where we have significant concentration of hotels like Boston, New Orleans, Dallas, San Diego and Seattle, so North America is a deceleration versus what we enjoyed in the third quarter, but also Latin America is a deceleration, largely because we have the World Cup in the part of the third quarter, we don't have that. And we know with the hurricane, we had in Cabos that we took couple of our properties out of the mix there, which were showing strong growth. So we don't have quite the same footprint in a strong growth region that we had for the bulk of this third quarter. And the last thing of real measure is in China we are seeing pressure on ADR. We're starting to lap the Sheraton Macau ramp. So I think there is enough, very tangible things that led us to believe that 3% to 5% range was the right range. Now, I didn't mention Europe, I do think that we had a strong base in Europe in the fourth quarter of 2013. And Russia continues to be weak for us. So I think we continue to feel like we're doing the right things and executing well and we're playing the hand we're dealt in terms of he geographic mix and this is a quarter where it's slightly weak. Relative to your point on 2015 in North America, we continue to think North America is the strong market next year and is likely going to be in the same zone as it has played out for 2014, so we don't expect a major deceleration or change in the North America trajectory. And I do think the one thing that we're cautious about is both the group activity going into the fourth quarter as well as group going into the years in the low-single digits, and that has given us some pause for; first, being more bullish, but frankly we think that the 4% to 6% RevPAR range for the total system is pretty attractive range. It's not far off of where we are this year, and where I think most people are externally. And so we feel like it's an aggressive one and we're seeing some share growth in there.
