My family and I are moving from Ireland to Seattle in October. We plan to fly to New York and then take a road trip across the rest of the way. We have two children under the age of 5. We would appreciate any advice/suggestions about best routes/family attractions and experiences of how far we can expect to drive each day with two small children. Also, roughly how much should we expect to budget for the trip? (ie rental car/gas/hotels/food etc) Thanks!
