Is it your first baby (I'm assuming it is) and how are you planning on feeding him/her?
Realistically I'd think unless you were early or on time it'd be a massive struggle. Firstly you may not have actually had the baby then - I was 15 days late when I gave birth, having been induced!
Secondly, it's bloody tiring - you will be getting very little sleep, with a baby that is likely waking every 2 hrs and will take an hour to settle. So you'll be getting an hour of sleep every other hour, and that's with a good baby! So you will need to sleep in the day to maintain sanity.
Thirdly if you're breastfeeding it can be really painful to start with and you'll likely be obsessed with getting the perfect latch, at this early stage neither of you are very good at it so you'll want some privacy to feed (every 2hrs!).
Fourth you may be very hormonal - your body does some crazy stuff post birth. I had a few days where I cried about everything!!
Fifth how thick are the walls at the hotel? Would you feel comfortable bringing a baby that will likely cry through the night somewhere where it may keep others up? It's just you probably won't need the added stress of feeling guilty about that when trying to fix whatever is going on with your baby.
Sorry I don't mean to be massively un-optimistic about it, but I think at best you'd have to be a maybe attendee. There are just so many unkonwns about when the baby will arrive, will it be a straightforward birth, etc etc. Even if it all goes smoothly I'd think it'd be most likely that you'd be too shattered to travel hours from home, with all the equipment needed for a new baby when you're only a few weeks in.
I'm two and a half months in and probably would feel comfortable going away now, but not in the first month! Going to the supermarket felt like an amazing achievement then or getting dressed before 12pm!
