I think we'll be having a wild spending month in September. My parents for 2 weeks, my in-laws for 10 days, my BIL for 1 week, and friends for 4 days all staying with us. Between more food, utilities, eating out, and activities, I have a feeling this will be a ridiculously expensive month. Arrgh.
What are the costs really associated with guests? I've found that besides a little increase in hot water, lights, etc, mostly it's eating out because you are too tired to cook. Increased gas usage from driving to see things or going to do activities. And basically paying for entertainment. Even if you pay for just yourselves, it's money you normally would not have spent on fun activities.
I think my budgeted $75/month fun money will be used up completely. Typically we don't spend it and we mostly use it during snowboarding season. But with this month I'll be going above and beyond in spending. Sadly I've already allocated an extra $1k for spending this month.
I guess I should add that for DH and I because our parents live far (over 3k miles one way), our visits are never weekend visits. And we have to do more and see more during that time. But it is nice to see family, I miss mine a lot so I consciously make a choice of spending more money on trying to see them whenever possible. To me it's just another line item.
I wonder if others spend as much when they have guests?
