Like many others, I'd suggest starting out slowly. A tent is certainly the cheapest way to go, but is totally different than an RV. We started tent camping with our daughter when she was about a year old. We then switched to a truck camper, which was way more comfortable. We then moved to a travel trailer, but it was too big to get to the more remote area we enjoy. We now went back to a truck camper, which is perfect for getting into more remote areas and towing boats or other toys. When we take the camper off the truck (seats 5), we also have a vehicle that can be used around town or as a daily driver. To us, this is a big benefit compared to having a dedicated Class B or C that can only be used for RVing.
With your Honda, I'd recommend staying with a tent, or rent a couple of different RVs until you're sure everyone enjoys actually camping and not just the idea of camping. If you can only afford one vehicle (trade off your Honda?), you may want to consider a truck that can be used for a truck camper (lots of info on www.truckcampermagazine.com/)or for pulling a trailer.
Have a great time!
