Honestly I thought that was a pretty good vlog from them. No Jenn and Baby J. A decent showing of what that tour offers. Tim back to excitedly showing off things he's actually interested in, instead of faking enthusiasm for shit he sees every single day. I enjoyed it.
Jenn, since I know you read here, this is what will help your channel continue to grow. Show off stuff like this. Stop it with the food shoveling closeups. Learn better descriptors than "delicious" and "refreshing". No more baby focused vlogs. Stay in the background. Let Tim do his Tim thing. This is what drew people to the channel in the first place!
Also, take a few editing classes. You can find a million free online. And find different music to play over water scenes. You've used that same song for every single water scene since you found it (AMI, baby splash pads, etc).
