to holiday with recently widowed MIL or not?

I hope Relationships is the right place for this: DP and I can't decide what the best thing would be to do here.

MIL was widowed earlier this year, and we are now wondering whether to invite her on our family summer holiday with us (me, DP, and two DCs (aged 4 and newborn). We both feel that she would benefit from a proper holiday, and that it is important to feel loved and wanted by her family right now. In terms of practical considerations, we can afford to include her, we all get on well, etc.

However, DP and I have had a difficult few years and feel we may benefit from a holiday where we can focus on each other and on our relationship. We have just had a new baby, after having had a stillbirth a couple of years ago. His father was ill for several months before he passed, and DP and I saw very little of each other during that time (as PILs live around 3 hours drive away from us). We understandably feel a little disconnected from each other right now, and it would be nice to spend a holiday getting our spark back.

Anyone else been in this situation? What should we do? Prioritise MIL, or focus on our relationship?

(If it makes any difference, DP is slightly keener on us holidaying by ourselves, I am leaning more towards inviting MIL)

Thanks for all the replies. It looks like the general consensus is that we should take MIL with us, but carefully manage expectations so that a joint holiday doesn't necessarily become a regular thing. (We did look into inviting her for only part of the week, but this isn't logistically possible, unfortunately.)
