I need it for mainly data for maps, surfing and such

It really depends on the level of data use. If its expected to be less than 100 MB/Day then I really would recommend this Spanish Orange deal which gives you 100MB at 1€/day in the countries you mention. See: http://www.prepaidgsm.net/forum/showthread.php?t=8459
Voice calls will also be very reasonable as they all are EU countries and there are price caps in place.

If its going to be more than 100MB/day (though unlikely if your hotel has decent wifi), then I would recommend picking up a local SIM in each country. Luckily all 4 countries have loads of SIM deals that are easy to buy at small convenience stores and supermarkets.
