I don't think I'd go that far! It's an added convenience, but my data already moves with me through the EU, since non-phone internet access (coffee shops, libraries, McDonald's, 7-11, hotels, etc.) is pretty widespread.
Currently I usually buy a prepaid data SIM if I travel to another European country. But this is a bother if you're going to be there just for a day or two.
Most cheap family-run hotels and all hostels have free and good WiFi.
Sucks for those of us who also like higher end hotels for personal travel, though.
