Hospital tour and breastfeeding class

S
How late could I wait to do these? 
I currently have a situation, my husband is having surgery July 28 (nothing major) with a 2 week recovery period. Puts us at August 11/12. All of the dates for the tour are either early August or late August. Pretty much the same with the breastfeeding classes. I'm due Sept. 8 and I refuse to be taking a tour on August 28th! That's cutting it too close. He wants to go with me and I don't want to leave him while it's still early into his recovery. 
I have no idea what to do.
