It is nearly impossible to find a clock in a casino. Casinos never close and their management does not want you to realize how long you have been in there or that it is time to go to bed. In fact, you usually can not even tell if it is night or day outside.
Carry a watch so you don’t loose track of time. A watch will help you from gambling way too long in any one session. It will assist in preventing you from missing your dinner or show. In fact, it might aid you to actually use your hotel room to get some sleep when in town.
Cell phones do show the time. But a watch is more convenient since you don’t have to dig it out to check the time. A watch is always available to see and makes it easier to keep track of time.
Don't forget your shades, your hat with visor...
Toiletries and Medical Supplies: Lots of sunblock...
Miscellaneous: And, a water bottle will come in handy.
