SGJ, you have far more self control than me, your FIL would have had a few choice words! Cheeky git. If he wants to stay in a hotel, he should have booked one. If he wants to treat your house as a hotel, then he needs to pay for it! 
Grinding pains, check! Bump emgaes for a few days, then pops back up, so I keep alternating walking normally, and walking like John Wayne. Flipping hurts, especially if I bend forwards suddenly and sort of push her down a bit further!
I've been getting crampy pains in the morning, asked MW who said that they fall into the range of normal niggles, but to call her if they start coming in waves, or getting stronger. The lo and behold last night, every 12 mins, 10, 8, then they stopped after a bit more than an hour. I am taking my notes to work with me and packing my hospital bag tonight! Not overly worried about an imminent arrival as I went into early labour with DD1 at 34 weeks, had an overnight stay at hospital, and everything stopped on it's own. DD1 then went on to be almost 2 weeks overdue.
As for visitors, I wanted immeadiate family to come and see us straight away, so had lots of visitors to the hospital. We only had one turn up at our home unannounced, but they refused drinks, brought knitted cardis, best wishes and hugs, and left soon after. When people asked when they could visit, we told them what times DD was likely to be awake and let them pick, and kept a sort of bookings diary on a white board! (DH has a BIG family, we had visitors every day) If people wanted to turn up during naps times I told them they could if thy wanted, but there might not be much point if they wanted to hold DD. No one ever tried to wake her up, I never felt worried that they would. I think perhaps the boundaries were silently written in when we "booked appointments" for people!
It didn't strike me at the time that I could have been considered rude, and tbh I still don't care if I was. Those first few weeks are so special, and I wasn't very well for a while, so everyone seemed very obliging. Once I could, we also went for lots of walks out, for fresh air, for a break. Never at the same time, so "poppers in" could end up sat outside for ages, which tends to put them off.
