I don't know where you live, but in my town it's very common to bring children to have a beer. The local brewery even has complimentary diapers in the mens bathroom. I count myself lucky to have that as an option, but even if I didn't I would see if friends wanted to go down to the waterfront to have a beer and let my kiddo run around happy as can be.

Travel is certainly more difficult than it used to be, but I've found that the types of trips I used to turn my nose up at (all-inclusive resort-ish) are appealing in a completely new way. We can put the toddler down to bed, set up a baby monitor, and go down and enjoy ourselves like we're actually adults, often meeting new folks.
