Fellow MN Scamp
owner, been there, done that...
You are more than 2 days from there! LONG driving days are called for to make it in 3 days! About 1600 miles from Mpls/St Paul.
Beware the cross-wind black ice in Iowa and Kansas!
We stayed at Isla Blanca Park as it was 1/3 the monthly rate of the KOA. KOA doesnt have any beach, Isla you walk right out onto it.
The wind NEVER stops on the island. Salt spray covers everything. Our cushions were removed for general cleaning and it looked like we spilled a salt shaker under them.
Camping is cheap on the beach, but be aware if tide comes in and Scamp
gets stuck its several hundred to get pulled out. Full-time job for big 4x4 pickups doing the pulling. Most bigger rigs park on sheets of plywood due to this.
We stayed thru Spring Break, the music still excessively loud until 4am! But never a problem with the kids themselves.
A hidden jewel is D's Pizza. Serves pizza and also a great spaghetti dinner.
On the island its self there is only one grocery store, priced accordingly.
We also staye a couple of weeks on Malaquite Beach, no hookups, have to move a little ways to dump. The showers are cold water only.
Since then we have come the last 4 years about 35 miles inland (Harlingen area) as half way between SPI and McAllen. Beach is 45 minutes away, anything else is within 30 minutes.
The Rio Grand Valley is known for its excellant hospitals for us "older" generation folks.
All the people are nice, never had any crime or other problems in the 8 years we spent winters here. If you go to Mexico, enter at Progresso! The other towns aren't safe.
By the way, its midnite now and its 74 degrees, but in 2 days a cold front arrives with lows in upper 30's!
