I would think based on how delay prone lga is the real problem is how late you might make it to your destination or if weather cancellation hotels near LGA
cost a ton especially after a few flights get canceled. The hotel rates are terrifying sometimes midweek even in advance at LGA
has much cheaper rates at least for the United passengers but it's such a huge hub that only lasts so long in bad weather if there's alot of cancellations. All the ny airports have pretty high rates and full hotels they can be rough hubs to get stuck in as expenses off airport can skyrocket. Getting stuck in say den or clt for example can be just tons cheaper obviously. I would bet LGA
has the most expensive hotels on average of an airport and not many good alternatives.
