Hi, we are coming into Niagara Falls in mid-April (got a GREAT rate at the Embassy Suites from Travelzoo - $96/night (US$) for a fallsview Jacuzzi Suite) and will have our kids with us - ages 7 and 4. We will be there for 3 days - 2 nights. In anyone's opinion, what are the two must-see must-do attractions that are appropriate for kids that age as well? Neither my husband or I have ever been to Niagara Falls, so we are completely clueless! Thanks in advance for any/all help and suggestions!
