Some people only want a hotel with free breakfast while others prefer to eat their morning meal at a local restaurant or bakery. If free breakfast isn’t important to you, don’t let that become a determining factor.
If you want a place with WiFi, read to see if it’s free or for a fee and if it’s available throughout the hotel or just in the common areas like the lobby. Also determine if the hotel has only WiFi, only a computer with internet available for use, or both.
Are you arriving late at night? Check to see if they have 24 hour reception. If not, sometimes you just need to notify the hotel of your arrival time and someone will let you in. But there are some places that are impossible to check into if you arrive past a certain time.
Look at things like the bed size and smoking vs non-smoking rooms. Does the hotel provide any toiletries or a hair dryer?
Not all of these things will be important to you. Pick a few that are essential to you, and eliminate hotels that don’t have all or most of what you’re looking for.
