HELP can I have a shower??

After seeing countless RHs, having major $$$ issues and headaches galore on who to invite.....FH and I are planning to just go away somewhere beautiful and get married inviting only our parents, sisters (we have one sister each) and their spouses.
What is the etiquette on having a bridal shower now? Women who will be invited to the shower will be not be invited to the wedding because we decided to invite our closest family only. Is it wrong for my MOH to invite my friends to the shower when they are not invited to my 'family-only' destination wedding?
