For any trip, list of certain items never changes. The only thing to bring and to pack is the special items that you need while on the way such as ski gear or fishing poles. Before going to pack any items, make a list of things needed for traveling to ensure you have everything. However, you will get everything on the road. So, buy the things whichever you forgot the items.
Pack the clothes for both day wear and night wear. For daytime, pack T-shirts, jeans and shorts along with one dress shirt, and pants, towels and possibly suit jacket for a nice dinner. If you plan for somewhere with tropical climate, then do not worry about dressy clothes, just you pack plenty of T-shirts because for most of the time you will be wearing T-shirts. You pack at-least one sweater since indoor areas can be cold even during the summertime.
