February or March?

[la79al]

I am not happy with the flights we got and DH probably isn't coming with us anyhow so I am considering changing our last week of February at ASMo to first week of March at ASMu. It would save about $100 on hotel, flights would be the same price, slightly better times. The kids would miss the same number of days of school. I know weather will be the same, wondering more about crowds and whether people think it is worth the switch of resorts.
