We're trying to decide if we want to rebook our trip to April (week of 4-18) or August (week of 8-15) next year. Easter is April 4th. Would April be a lot more crowded or similar to August? Would flights and hotels cost a lot more in April? It's too early to look up any rates. We would like to go in April but not if it's significantly cheaper and less crowded in August. Thanks!
