Not all that long ago, fancy technology like what we have today was pretty much inconceivable for people once all has been said and is now out of the way. Hence, they often needed to get really creative while coming up with things that they could do in order to pass the time. Looking into what people used to do in this regard can be quite useful for you in a charter bus, and the reason behind this is that you would need to figure out what you can do to make the time go by faster since charter buses usually take you on really long rides that might require you to take a nap since there would be a real shortage of fun activities that you can end up taking part in.
If you want to take a leaf out of the book of people that came long ago, you might want to give cloud chasing a try. This basically involves looking out of the window of your Seattle charter bus and seeing all of the clouds that are going by. If you look closely enough this might just enable you to see shapes in the clouds which is something that will provide a lot of fun not just for yourself but for whoever might be sitting next to you as well.
This will make it so that the duration of your journey will seem a great deal shorter than might have been the case otherwise, something that would enable you to get the most out of the experience all in all. You will get tired of watching movies and listening to music after a time, so this can be a nice change of pace.
