I'm sure others will come up with additional suggestions, but we had to wing it when packing for the driving trip. We stayed in a hotel after release from hospital and this bag of items all came in handy:
-Small wastebasket to keep Foley catheter bag upright. (Looked all over for a very small one - finally found one at a "dollar" store with molded handles)
-Surgical gloves (all the catheter info said was to "wash your hands." Gloves really were easier to deal with - in addition to hand washing.)
-Antibiotic ointment - we took it, but the hospital provides a tube.
-Old sheet, washcloths, and towel - hotel sheets are white and there is some blood leakage following surgery. The folded up sheet was for underneath. Laid a washcloth over catheter/penis and then a towel to prevent leakage onto top sheet. At that point, husb. did not feel like wearing pants/pajamas of any type. (Although I had slit an old pair and re-Velcroed for that purpose.)
-Gallon freezer bags - there are simply some things hotel staff do not need to see or deal with. The latex gloves, bloody tissues, and empty enema bottle (from the night before surgery) were stashed in the bags and disposed of at home.
-Generic stool softener - less expensive than prescription type and better to have everything on hand if possible.
-Small bottle of vinegar - for rinsing out leg bag and replacing with overnight bag. Used the leg bag to go from hospital to hotel.
One last thing. We took a small travel bag with a shoulder strap and top opening. If you're self-conscious about leaving the hotel, just run the bag through the pants leg (this style zippered at bottom) and into the travel bag. Can carry by the strap and it's much less obvious.
P.S. Hi, Spinbiscuit - glad to see you back from your second round of hernia repair. How did it go?
