So many factors to consider, every family will have a different view. I am just in the middle of booking our hotel for August offsite, costing me £32/nt incl breakfast, Wifi, parking & lots more. Food costs us approx £60/day so we will be paying about £90/nt, again my table below, upto 2012 at £118/nt it was worth staying at OKW, this year at £147 was too high for me, next year way too high at £160.
I have really enjoyed doing
DDP for the past years but last year I found myself getting wound up with the prices, auto 18% tip, increased menu costs, etc, our meal at Sanaa we bought a starter, a couple of drinks and tips, it came to as much as a complete meal with tips offsite. The costs were so high I couldn't relax and enjoy as much as previous DDP trips. I also think service suffers slightly with parties of 6 or more.
Saying that if you prefer being onsite and doing DDP, have 4 in a room then it can work out a reasonable option, thankfully we enjoy staying offsite and dining offsite as much.
