I don't think you are being unreasonable or a snob, but I do think you and your friend should reach a compromise, you said your friend has been through a lot, maybe a week or two doing nothing is what she feels she needs right now, however, if the holiday isn't for a while, her view by the time the holiday comes around may be different. Why not say doing nothing isn't for you and you will go if she can reach a compromise with you that you can take a couple of trips and do a couple of activities whilst away, find out as much info as you can on whats available in the area, and just say we can make a rough plan such as the first two days (day and a half) relaxing, then a day exploring a day relaxing, next day do an activity for example,
I've done all board basis holidays and I much prefer the freedom of self-catering yet I hate having to cook and wash up so we usually go half board, if you miss a meal you don't feel you've wasted as much money than if you miss a day with all meals and drinks included. the best part of AI though is not thinking about what to make for dinner where to go. and my DSS can go get himself as many drinks as he likes without hurting the spending money.
i do think you should go and you may be pleasantly surprised that you actually enjoy sitting around chatting delving into a good book more than you realise,
we have had a really tough few weeks (last 3 years have been hard with serious illness for me) in our house we had a really sick dog and then we lost her (she is like my child) then my DH had long awaited (3 years) foot surgery so is unable to do anything to help me out around the house, (his foot is at risk of collapsing if he puts weight on it) therefore i am run completely ragged, I'm exhausted and not in the best of health myself, (cancer remission and post-op hysterectomy)
my DMIL and DFIL said on Sunday that is it, we are taking you away (Rhodes) when they said all-inclusive I was a little like oh no and boring as they are the types that do NOTHING on holiday (they work extremely hard) and that isn't for me, we love exploring doing activities, shopping, yet in the same breath i was like oh god yes we need it!
DH thinks there isn't much to do there and will be bored. my reply was i quote " you can't do anything anyway, I'm dead on my feet at the moment running around doing everything, which I know is annoying you because you feel its your fault its not, Nephew can keep DSS entertained, we've had a great action packed holiday already this year, plus I'm sure if I ask nicely, your mam can have DSS one night for us so we can have some aallooooone time
" at that he was sold haha!!
there is a total of 6 of us going including DSS and nephew. (can keep each other entertained) when i explained to DH we where AI he said well at least you can have a break you need it, (it's killing him he can't help me)
ive lost where i was going with this........ oh yeah, although you say its not for you, you dont know what is around the corner and by the time the holiday comes around you may actually need a week or two of doing nothing, and again you can always make a compromise with your friend every other day or every few days she comes along with you and does site seeing, activities etc jst be honest with her, or even consider going half bord so you have meals included on the days you stay at the hotel. im sure she would much apprecite you making a compromise with her to go than not going at all .
