Well, I think you need to think about how you normally eat at home. Do you usually have a sit-down dinner every night? Are you okay with eating fastfood/cafeteria type food for 7 days? I think answering those questions will help you decide. Personally we did upgrade last December and spent about $300 in 10 days on tips for a family of 4 (2 adults, 2 kids)...not sure how many adults/kids you have in your party, but that makes a big difference as well. For us it was about having a good sit-down meal at least once a day, for others that might not be such a priority. Good luck!
