Residency
You'll be find on your NV CFP as long as you do not get a Florida DL, register to vote in Florida, file a declaration of homestead in Florida or do another statutory act which makes Florida your domicile. The exact Florida Statue is 790.015 (3).
You have a 90 day grace period under the same Florida Statute once you get a Florida DL. I would not get your Florida DL while you are living in a temporary residence (i.e. hotel). Until then you should be fine under your NV CFP providing you keep your NV DL.
Your NV CFP training certificate will be accepted as proof of training for your FL CWFL.
Know the law; don't ask, don't tell.
