I go camping so i don't mind roughing it even with kids BUT when we plan a weekend away we tend to choose somewhere with good kids facilities - more for the fact that some days while DP and I want to do very little we still have kids to keep entertained.

A great pool or child minding service (if you want alone time) is worth the extra $$ in my opinion and really it means you can save yourself some $$ by spending a day at the hotel rather than out on the town. IYKWIM.

Is there a huge difference in pricing? If it's say $100 total i'd go the more expensive option and enjoy some quiet time at the hotel.
