Yes. Chris good morning. This is Colin. So let me give you sort of a 30,000 foot view of group because we know there has been some commentary of recent that has led to speculation sort of there is been sort of a weakening here in group. So for us, we do not look at group as sort of a homogenous bucket. Group types can behave very, very differently and our hotels understand that and as does Marriot and that is my we have a very different sales structure by group type. So what we're seeing in group by category will be as follows and this by the way relates to forward bookings. So large groups looking to book for 2018 forward, and I know you didn't ask that question, you've asked about short-term stuff. As you'll have seen from what is occurred in our first quarter, what occurred last year is that this sector is very, very we see it as very strong. And what this has led to is we’ve outlined this morning in our earnings call, which we've just done here, our inventory of forward room nights has grown over the last 12-months by over 600,000 room nights, which is an awful lot of room nights. I mean that is a staggering amount of room nights that this forward inventory has grown by, and by the way, if you remember the Smith Travel analysis of last year, where Smith Travel looked at between the years of '13 and '15, what they pointed out is that large groups are growing very, very healthily. So there's no change to that. We're very, very happy with what we're seeing. Now in the short-term small groups, particularly Corporate, we have seen some volatility in the willingness to book. But frankly, this was a pattern that emerged in the second quarter of last year which we pointed out, I think, Patrick in our second quarter earnings call last year. But from our perspective, this is not something that's keeping us up at night. We have seen two or three months where we book at historical pace and then one or two months, where we are slightly below it. The first quarter of this year, our in the year, for the year, short-term stuff was there or thereabouts to historical pace. I think I'm accurate in the analysis, Patrick. So, in terms of current group behavior, I would describe it as steady as she goes. In terms of current group, steady as she goes, where we're not seeing groups change their behavior in terms of attrition. We're not seeing groups change their behavior in cancellation. We did have the one cancellation that was 7,000 room nights at Opryland, but as Mark pointed out, we're going to collect $1.2 million to $1.3 million of cancellation fees and we think.
