I am staying at a hotel near my venue, about 3 minute drive. My venue has an exclusive full use wedding booked the night before so I can’t stay at the venue.
Like you my parents house would be full and I decided I wanted a relaxed morning getting ready. My Mum and bridesmaids are staying with me.
Whilst I understand the venues rules, one month before doesn’t leave you much time to find somewhere else if you can’t stay there.
