Hey Jersey Gringo, welcome!
The middle of July is called veranilla - "little summer," and it's the driest part of the rainy season.
Yes, you can do many interesting day trips while still based in San Jose. Your hotel will have a tours desk to help you, and also there are many toyur operators who sponsor CRT. Go to the Discounts section and check out the ATV tours, canopy tour and sport sihing activities.
HDR - Hotel del Rey does have some adjoining rooms. Why not go to their website for rates?
I know you and your friends will have a ball. Be sure to ask anytime, if you have further questions. BTW, smart move joining the VIP. If you stay at the Amon Plaza, Presidente or Sportsmen's Lodge, you'll save the cost of your card in a short stay, as all these hotels offer CRT VIPs an excellent discount (the Hotel del Rey does not, and they charge $10.00 per chica per visit to your room).
Again, welcome to CRT!
