Hi All,
My husband, baby and I are coming to the US (from Australia) in Dec to spend Christmas with my brother's in-laws in CT. We plan to spend 4 nights in Washington DC prior to travelling to Southbury, CT on Dec 23 (a Saturday this year). We have a couple of options for travel, but without having any idea of traffic etc. I have no idea what to do:
1) Pick up a car in DC and drive all the way to Southbury, CT. Aim to leave early in the morning on the 23rd.
2) Catch Amtrak to NYC, pick up car in NYC and continue on to Southbury by car.

What do you suggest?

We will be in Southbury for 3 nights and then have to travel back to NYC on Dec 26th to drop the car off before flying to Montreal. We have the option of returning the rental car and flying out of either LGA or EWR airports - any suggestions of which airport is would be easier/less traffic to get to considering we will be travelling from Southbury? How much time should we allow for travel to the airport on Dec 26?

Any advice would be greatly appreciated!!!!
