I just received this information from NCL:
Norwegian Dream (October 22 sailing out of Houston) will now call into Veracruz, Mexico on Monday with an overnight stay and spend a full day there on Tuesday. The ship will spend a day at sea and call into Progreso on Thursday and return to the Port of Houston on Saturday.
Norwegian Sun (October 23 sailing out of Houston) will spend two days at sea, then call into Belize on Wednesday and Roatan, Honduras on Thursday as scheduled. Subject to Hurricane Wilma having moved well away from the Yucatan Peninsula as predicted by Monday or Tuesday, Norwegian Sun will then call into Cozumel, Mexico on Friday if the port is open for cruise passengers. The ship will return to the Port of Houston on Sunday.
As of now, all other NCL vessels will sail as planned.
Hope that helps, but I will send the link to your home e-mail as requested.
