Trip to midwest, should I cancel?

Wife wants to make a cross country road trip with us driving to Wisconsin from California with 5 dogs in a midsized SUV that I have. I feel like round trip, that will be a lot with luggage, Crates, and everything else. Cooler, food. She sounds excited like a kid but I already travel 2.5 hours per weekend to see her until I transfer and we move in together. How do I cancel without the fear of her throwing the decision in my face or making me feel bad. Or should I just go through with the trip and make it work, happy life happy wife?
