Hi SMB&CRZ,
Both my mom amd my MIL were definitely hesitant about the whole DW concept- I ended up taking my mom down for a site visit in November before the wedding (Jan) to finalize everything, and so she could see we were not dealing with a totally undeveloped country, etc.- it was the best move I ever made! She came back saying "hola!". That being said, even if she hadn't been able to come down prior, i knew she and everyone else would love it once they got there, and some would stay skeptical until they arrived- that's just how some people are (afarid of change, etc), and we can't change them- so don't let them get to you (but also don't expect them to be supportive until they're at the resort, that way you won't be disappointed ). Hope this helps!
