Depending on what part of the world you live in the seasons you experience will be different. If you live in the United states you will usually experience 4 seasons, spring, summer, autumn and winter. Growing up in the islands I was only exposed to 2 seasons, rainy season and dry season. There are some seasons and events that are celebrated all over the world though, one of them being the ringing in of the new year and the other being Christmas. As far as the Christmas holiday is concerned, most countries celebrate it at the same time of the year, with easter falling at the same time also. A big opportunity to entertain yourself is the famous carnival that can be experienced up and down the islands, with spill over in Miami, New York, Canada and smaller events showing their support in other states. There are always things to do at these events and depending on the time of the year it comes to you, (or you go to it) the season will be what you make it.
There is nothing worse than having to think about water proofing your basement, especially if finances are on the tight side. There are many homes that come complete with a basement, unless of course you happen to live in the sunshine state then the likelihood of a basement in your building will be slim. I guess you could have a crawl space under the house and think of it as a basement, but it will do you no good if you are thinking of renovating it so that you can entertain your guests or just use it as a play room for the family. Whatever you decide to use your extra room for, the last thing you want to find is water in the basement. If you own the building there are all sorts of changes that can be made to your play area and after finishing the basement it will be time to think about some bar ideas, non alcoholic of course.
