Eric gives great advice. I would just add, that if you are there the full week try to get out into town or on some adventures. The resort is fantastic and you will have plentiful options for meals for the full week. If you plan on eating at the resort restaurants, particularly the more upscale choices, get the meal plan booklet. It will save money.
In terms of some off the resort ideas: Nuevo Vallarta marina is close by and if you are mobile, you can walk along the beach (away from Pueryo Vallarta) to the jetty and then onto the road to get into the marina and some nice restaurant options. We like Eddies Place for a very casual meal. A tai into Puerta Vallarta is not too expensive. It is a bit of a hassle to take the shuttles to the taxi stand, but there will be taxis on call and it is about 20 - 30 minutes to get into PV depending on traffic. You can stroll along the Malecon, the beach boardwalk, and there are touristy shops and restaurants. Also. lots of restaurant choices in town off the Malecon from very local to very upscale. It you are adventurous, then you can go on one of the Vallarta Eats food tours. It is a walking tour at lunch or dinner and they will take you to many different local spots. It is a lot of fun and a great way to explore a new town.
Vallarta Adventures is located on the way to NV marina. They offer many tours in the area including snorkeling, scuba, boat, whale watching, ATV, jungle, tours and many more. We have had terrific experiences as their guides are usually exceptional.
The time share presentation is ALL day. By the time you have breakfast, do a tour and then sit in the sales room, it is 5 hours minimum. You will lose most of a whole day of your vacation.
