Transportation from Granada to Sevilla
 

I'm spending 2 days in Granada and 2 days in Sevilla. Is it better to rent a car to travel from Granada to Sevilla? Or should I take a train/bus?

Also, if I only have 4 days, any thoughts on whether to spend more time in Sevilla vs. Granada?

Thanks!

Two and two you can’t really change, that’s a full day only. Trainn time 3:22, booking on the renfre site.

The absolute must-see in Granada is Alhambra, and you want to spend the best part of the day exploring the complex (it's quite big), so you need two nights. I would spend more time in Seville but you only have two nights left.
There is no point in driving, unless you wish to visit somewhere en route, such as Córdoba. Train requires a bus connection first to Antequera, so it's better just get a direct bus, which takes about 3 hours.

Also, if I only have 4 days, any thoughts on whether to spend more time in Sevilla vs. Granada?>

After being in both a couple of times Seville hands down- stay just one day in Granada - trains are good but check also buses that may be just as quick and even cheaper than the cheapest train fare - for lots on Spanish trains yes www.renfe.com - the official site of Spanish Railways and for general info also www.seat61.com - expert advise on booking on renfe.com and alternative sites that are easier to work with similar fares; www.ricksteves.com and www.budgeteuropetravel.com.

What are you doing before Granada and after Seville? If just going to cities trains are best - if wanting to drive thru the countryside leisurely rent a car. Cars are useless in cities like those though.

I'm dying to go there one day!
