I will be taking another trip this summer to the Florida coast and will be on a fishing charter with my family but we won’t be in the ocean but In-shore so there will be more calm waters, what should I take ahead of time to prevent seasickness?

Paradise 4 Paws is a boarding facility for dogs and cats located in Schiller Park, IL. Has anyone brought their pet in here and how was the experience? ...I'm nervous about leaving my dog in any type of kennel because they remind me of animal shelters (they're all in cages) and it would make me sad leaving her in a cage... but this place is different they all have their own room with a bed and a web cam and the presidential suites have a TV too. My dog is going to P4P in August and they won't allow raw-hides. Are there other types of chewing things i can give her that will be okay?
