Mizuho lowered the firm's price target on Marriott to $260 from $263 and keeps a Neutral rating on the shares. The analyst cites a more conservative view on RevPAR ahead of the Q1 report for the target drop. RevPAR trends have been slightly weaker than previously modeled, primarily in the United States, the analyst tells investors in a research note.
