I prefer gamble alone through online gambling sites. Online gambling offers a better privacy and flexibility. We can gamble any time and any where. This fits with my gambling style. This is something that we can't get through physical casinos.

If your concern is about maintaining social interaction or friendship, we can do it through other ways. Take a vacation together with friends or family members or gather with neighborhood will be a more effective way to maintain social interaction and friendship. Meanwhile if you mean it will be more fun gambling with friends, I don't think so. Some people even don't want their friends know their gambling activities. Moreover if they win big prizes.
