Price the holiday separately and together. Look at the different choices of accommodation available. You might do better with cheap airfare and an Airbnb property. Watch out for car rental versus public transportation. If the area you are going to has a good public transportation system, you probably won’t need the car. If it is more isolated, get the car.
Check the meals with the hotels. Some offer breakfast every morning, and some offer free happy hour and early bird dinners. If you like to eat early and/or have kids, the early meals can be ideal.
