have been in 2 minds about whether to start this thread or not as i guess it's more of a WWYD?
DP and i are booking our summer holiday soon. i haven't been abroad since 2008 and i'm really looking forward to it. i lead quite a busy lifestyle and don't get as much quality time with DP and DD as i'd maybe like... anyway.... whenever we mention booking our holiday MIL says "let me know when you book it, FIL and i will come with you. we'll get a room next to yours and have DD so you can both do your own thing for the week" 
thing is i don't want to do our own thing, i want the 3 of us to spend quality time together and enjoy DD's first holiday, just the 3 of us.
i love MIL, she's a nice woman who means well but we're quite different, she's a bit boring i'm afraid and i don't fancy a full week in her company. we had a weekend away with inlaws once and it was so tedious, plus they would bang our door down at the crack of dawn and demand that we all have breakfast together. FIL is also lovely but i would never leave DD with him "to do my own thing" he's way too lax and a bit docile.
MIL has suggested it twice now and i've said both times "that wouldn't be much of a holiday for you having to care for DD, you might as well book your own summer holiday and relax and enjoy yourselves" DP just walks out of the room!
AIBU to ask DP to tell them straight we just want it to be the 3 of us? would i be better just booking our holiday and not mentioning it to them? WWYD?
