Pls help - want to travel wirelessly and ckeck emails

Pls note I am not a Techie and this might appear to be a stupid
question.
But I need help.

I have
1. Comcast for my wireless internet - laptop and
2. T mobile ( motorola razor) for my cell service.

For temporary traveling purposes with my family on vacation, how can I
access my emails via my laptop.

Where do I start ?

What equpiment do I need ? What service ? Which company ?

Since I need this service for less than a week.... what suggestions can
anyone  give me ?
Of course I would like to be economical too.

I have heard of hotspots...

Since I am traveling with my family on vacation, I do not want to have
to drive them every 2 hours to the nearest Starbucks etc. to check
emails.

It would be nice to be able to do this while we are driving.

Any suggestions ?

Thanks
Rita
