No coolers.
Don't know how the traffic will be coming in from Puerto Rico.
If you have to come in from the south (e.g., through Austin) you can hit bad traffic in the mornings and afternoon of if there has been a wreck, or if construction has lanes closed... Coming in on I-35 from the north there shouldn't be much of a problem. Not too much construction going on and the morning rush hour is over by 9 a.m.
