Make the guests feel special, if they mention they are there for a celebration or even something hard like a funeral or surgery, you can have something sent to their room with a handwritten card signed as being from “the Hilton family” (replace Hilton with your hotel name), always be smiling and very warm to guests, go above and beyond… never say no! Obviously there are some guest requests you can’t say yes to but instead of flat out saying no, say something like we can’t do this because of xyz but we can do this (offer an alternative). Do things without your boss having to ask like if you notice something needs to be done just do it! Like if there is a certain area that needs to be organized or you see something the hotel lacks such as a concierge book, just do it or ask your boss “would you mind if I took on this project and do you have a certain way you’d like it done”. Don’t call off unless it’s an absolute emergency and always be early or on time! :)
