@Carol-Lee1, I think it might be worthwhile to leave some basic breakfast items for your guests. Here is what I leave:
1 package of 6 English muffins, usually about $2 (if it's a big group I leave two packages)
5-6 jars of Bonne Maman jams - $4 each, last through many guests (I also have about 2-3 jars of sugar free jams from other brands - they do get used too)
1/4 butter (half a stick usually plenty), about $.75
jar of peanut butter and jar of almond butter (lasts through many guests)
either half pint of 1/2 1/2 for coffee or half quart of milk (for British tea drinkers or family with kids)
Keurig coffee pods (Kirkland Bold from Costco - about $0.33 per cup) and a range of teas including herbal, fruit, and black tea
sugar, packets of Splenda and Sweet and low
I think I spend less than $6 or 7 per group of guests on these breakfast items and they often mention how "everything was provided"
I also almost always have fresh flowers from Trader Joes' - $4 per bouquet
Also have some packets of "famine foods", such as instant oatmeal and ramen noodles (surprisingly popular!) in the cupboard for starving midnight arrivals. I also provide them with spices, oil and vinegar, and condiments like ketchup, mustard, mayonnaise etc. in case they want to cook. These last through many guests.
Hope you enjoy your hosting experience!
